Essential Aspects To Consider While Hiring Roofers

A roofer is an individual who specializes in roof repair. They usually check the whole process of roofing at residential as well as commercial buildings. They scrutinize the building plans and ensure that the roofing is performed according to the original design. It may be hard for you to understand the complete roofing procedure, but a roofing contractor will explain everything to you in detail. Roofing Contractors Sacramento will work on your roofing and give suggestions to prevent future roof problems. There are many aspects of roofing that need careful attention. For example, a good roofers makes sure that they finish the job accurately and within the specified time period. Moreover, they use quality materials and employ appropriate methods and techniques during the job estimating. For this reason, you must hire only the best roofers or roofing contractors. Here are several tips for you to get the right contractors for your new roof. When hiring roofers or contractors, always choose reliable and licensed professionals. Do not go for those who do not have license because this can lead to major problems. Also, check whether the roofers have insurance coverage. Insurance covers damages, accidents and injuries to employees and property. Before hiring a roofing contractor, you should first know about his insurance requirements. You should also verify whether your roof needs to be replaced immediately or not. As roofing service provider, your main task is to provide a safe and secure environment for your tenants and visitors. For this purpose, always provide quality services. Keep in mind that the safety of your employees and property can be affected if you hire an incompetent roofer. Therefore, you should choose experienced roofers or roof construction companies who have built a good reputation over the years. You can check whether the roofer or company has achieved certification or accreditation from a leading national or local association. Another important factor when hiring roofing contractors is to consider the type of job that they are expected to perform. There are different types of jobs that can be performed by a roofing contractor and all of them require different tools. Therefore, it is important to know what kind of job they will be doing. This will help you determine their skill level. If they are experienced with certain tasks, then it is better to hire them but if they are not skilled, it is better to look for someone who is. Apart from ensuring the safety of your residents and visitors, roofers also play an important role in maintaining the general condition of commercial buildings. The roof of commercial buildings often bears the brunt of natural calamities such as strong winds and heavy rains. This means that your roofers need to be able to work under difficult circumstances. In order to keep the building intact, roofers need to ensure that there is no water seepage. They must also be able to clean up debris properly and prevent any bacterial infestations. Apart from this, roofers also have an added responsibility of providing aesthetic appeal to the building they are working on. This is where roof construction companies come into the picture. By hiring an experienced roofing contractor, you can ensure that your roof construction project goes smoothly. They are trained to take care of all the aspects involved in roof construction and so you can get your desired roof without any hassles whatsoever. The best part is that these roofers work closely with architects and interior designers to ensure that the final result meets your expectations. Another important factor that you need to consider while hiring roofers is their honesty. It is important for you to hire roofers who are committed to the work and ensure that they deliver quality work. If you choose roofing contractors who are not well established and who lack experience in the roofing industry, then you might have to face a lot of complications later on. For instance, they might start building your house at a site that is not ideal and so they end up incorporating features that do not suit the location. Also, you need to check if the roofers have the necessary license and insurance to carry out the work that they have been hired for. All these aspects will ensure that your work is carried out in the right manner and you can rest assured that your home is in safe hands.
What motivates one to install solar panels?

We live in a world where electricity is very important. We need electricity to power our home appliances, mobile devices, computers, laptops and others. Electricity has become an inevitable part of our life. As the demand increases, its cost also hikes up. This makes people look for alternative sources of energy. Of all the resources of renewable energy, wind and solar are the ones that are widely depended on. Solar power has become a trend in renewable energy It is a fast-growing industry in Australia. The government of Australia has given utmost importance to the green movement. As part of bringing down the power cost they offer subsidies and incentives to residential and commercial sectors. By producing their own energy, they can become energy independent. For harnessing the power of the sun and turning it into electricity, one need to install a solar power system. With over 2.77 million solar PV installations, Australia has changed its energy profile. It is now a strong leader in Solar PV development. There are many reasons why people abandon their utility power companies and make PV decisions. One of main reasons why people turn to solar energy is the hefty electricity bill they receive from the utility company. It is a massive shock that one has to undergo every month. By installing solar panels one can stop worrying about the sky rocketing power prices. It is the aversion to pay high to the utility company that motivates many to install solar panels. Utility companies charge high for the low concern electricity generated by them. Installing solar panels is a legal alternative to make zero electricity bill. With a judicious use of solar power system, one can literally eliminate or reduce electricity bills. A top quality 5kW solar system can reduce around $2000 a year on the electricity bill. It saves tens of thousands of dollars over the life of the system. Another reason why people go for solar panels is to save money. Besides reducing electricity billsinstalling solar panels helps to maximise the returns from their investments during the lifetime of solar panels. In Australia most of the solar systems pay for itself within 3 to 5 years of installation. A 5kW solar system yields a total profit of over $50,000 over its lifetime. While installing solar panels, the solar company takes into account the roof size and orientation, cost per kW and the energy consumption profile of the client. An apt and efficient solar power system will be cash flow positive from day one. A solar power system helps one to save money in two ways. One is by offsetting the energy consumption and the other is through feed-in-tariff for the excess energy produced by system. A solar feed-in tariff is an amount the client is paid for solar electricity exported from their PV system to the mains grid. It varies from state to state and retailers. On average, it is around 10c per kWh. Net metering is the foundational and most effective solar policy on which the entire residential solar industry is built. It allows feeding the surplus electricity generated from the solar system back to the electricity grid for later use. Net metering helps one to reduce their electricity bills and save more. Many people consider installing solar panels as an asset. A good solar system increases the property value. According to the National Renewable Energy Laboratory, a solar power system that saves $400 per year would add a value of $8,000 to that home. Almost 57% of homeowners are ready to pay up to $10,000 more for a home equipped with solar. On an average, homes with solar panels sell for 4.1% more price when compared to homes without solar. A solar powersystem improves the environmental rating of the property, thereby attracting environmentally conscious buyers. It increases the potential rental yield. The tenants can benefit from the free energy on roof. There are many who look for rental properties with solar panels. It relieves them from depending on fickle public utility companies for power. Another motivating factor to go solar is the frequent grid power failures. Climate changes and grid instability cause frequent power outages and blackouts. Climate changes result in natural calamities like severe storm, heat wave, wildfire etc. It can cause the grid to be down for weeks. An increase in global demand for electricity, aging transmission infrastructure and a change in generation landscape due to the increase in renewable generation are some of the reasons for grid instability. If a battery storage system is added on to the solar power system, one can have the benefit of having power even during times of power outages or black outs. With battery storage system one has the ability to operate off-grid. It can make life safer and easier. It can provide light, running water and heat even if the grid fails. Many people turn to solar installation with a good intention of saving our environment. Going solar is a first step towards making a cleaner and greener planet. A solar system protects the environment by reducing global warming and climate change. It is part of reducing our carbon footprint. It protects the environment for ourselves and for our future generation too. It fights climate changes in a big way. By replacing fossil fuel powered electricity with carbon free electricity produced by the panels one can have an assurance that they are doing their bit to save the planet. A solar system allows one to live an extravagant life style. With a solar system, one need not bother about power charges. One can run Ac whenever they want, light up garden at night for long, can run swimming pool pump for hours, don’t have to worry about lights and fans being switched on for a while. It helps to improve the lifestyle of the family. They don’t have to be parsimonious with electric usage as it doesn’t cost them a penny. Hiking power prices, dropping solar prices, reasonable tariffs […]

NSW stuns with 34GW of wind, solar proposals for New England renewable zone

A call for expressions of interest to build out the New England renewable energy zone in northern New South Wales has been “swamped” by 34 gigawatts of proposed projects – more than four times the capacity needed for the planned 8GW zone. The New England REZ, based around Armidale, is one of at least five renewable energy zones planned by the NSW Liberal government to replace its ageing coal fleet, most of which is expected to retire in the next 10 years. State energy minister Matt Kean said the EOI attracted more than 80 registrations of interest, which showed huge investor confidence in the state’s Electricity Infrastructure Roadmap. “The overwhelming response shows this is a once in a generation opportunity to attract enormous investment into regional areas, cementing NSW’s renewable energy future,” Kean said. The minister said the REZ was expected to deliver around $10.7 billion in investment and around 830 operational jobs, as well as 1,250 construction jobs each year, while also pushing down electricity prices and providing landowners with alternative income streams. While the New England REZ is the biggest in the state, the Central West Orana zone, located around Dubbo and Wellington, attracted an equally impressive response of 27GW wind, solar and storage proposals for just 3GW of capacity in its EOI last year. NSW is also looking at REZs in the Hunter and Illawarra regions, and in the south-west of the state. Formal auctions of capacity and positions in the state’s various renewable energy zones will begin in 2022.

Japanese eco-tourism resort taps ClearVue solar glass for greenhouse

The patented solar glass technology of Australian clean energy innovator ClearVue Technologies has been selected for use in a greenhouse at a high-profile eco-tourism and “wellness” resort in Japan. Perth-based ClearVue said last week that it had received an order for 187 of its glazing panels, to be integrated into the roof of a strawberry greenhouse at the Aqua Ignis Hot Springs project in the Fujitsuka area of Wakabayashi-ku, Sendai City. ClearVue’s technology incorporates a clear lamination layer between glass panels that drives the incoming wavelengths of UV and IR light to PV cells located around the edge of an integrated window unit to generate electricity. As the company has demonstrated with a “world-first” clear solar glass greenhouse at Murdoch University in Western Australia, this is ideal for agricultural applications, as the clear glass lets in natural sunlight, while diverting the wavelengths that can be harmful to plants for conversion into power. The solar greenhouse at the Aqua Ignis project is expected to generate around 8,573kWh of renewable energy a year based on modelling for the region, while also contributing to the eco-tourism credentials of the resort. “The Aqua Ignis Hot Springs project… is set to become a significant tourist attraction in the region with visitors able to visit the strawberry greenhouse and experience ClearVue’s world leading solar PV glazing solution,” ClearVue said in a statement.

Sun Cable: World’s biggest solar and battery project is about to get a lot bigger

The world’s biggest solar and battery storage project, planned for Australia’s Northern Territory and backed by billionaires Mike Cannon-Brookes and Andrew Forrest, is about to get bigger. The Sun Cable project, which started out as a 10GW solar project in 2019, has expanded to plans to install 14GW of solar PV, 20-30 gigawatt-hours of battery storage and a 5,000km transmission system linking Darwin and Singapore. But the company behind the project, also called Sun Cable, has been crunching the numbers on scale and technology costs and is expected to announce the details of a further expansion later this month, and possibly reveal some new customers. “The project is getting bigger,” Sun Cable CEO David Griffin told RenewEconomy. “With the passage of time we have been able to undertake a lot more research into the nature of the… solar resource and the technology roadmap for photovoltaics and storage, and the load profile of our prospective customers. “When you put all that together, that demonstrates we can achieve a significantly larger installed capacity at that site and, to some degree, it would be optimal to do that to better serve the loads we are seeing.” Griffin would not say by how much the 14GW capacity of the solar component would increase, but said that the battery storage component – previously estimated at between 20 and 30GWh – would increase accordingly. The fact that Sun Cable is looking to deliver up to 800MW to the Darwin grid by 2026 is significant because it points to a major new customer for renewable energy as the local grid currently has average demand of just 150MW.

How to claim solar rebate?

Solar rebates are subsidies or financial incentives given by the Federal government to boost the solar power business of Australia. Government rebate solar Perth is in the form of STCs. The value of STCs is used to offset the upfront cost of solar system purchases. The government creates virtual pieces of paper called Renewable Energy Certificates (REC). When one buys a solar power system, the government awards a certain number of REC. For every unit of renewable electricity generated, an equivalent number of RECs is produced. The RECs that a residential solar system receive are called Small Scale Technology Certificates (STCs). These RECs can be traded with fossil fuel generators for cash. Each STC has a monetary value that fluctuates between $34 and $40. To claim solar rebate Perth, WA one has to be eligible for it. Eligibility for claiming the solar rebate changes from state to state. To qualify for solar rebate Perth, one need to own a small-scale renewable energy system such as a solar panel system or solar hot water system. It has to be installed at an eligible premise like houses, townhouses, residential apartments or shops. The solar system must be a new and complete unit and there should not be more than one system at an eligible premise. The electric solar system must have been installed no more than 12 months prior to the date of application for STCs. While replacing an entire solar system, the new system is eligible for STCs. If one is replacing the panels alone, the system is not eligible for STCs for the new panels. It is because the panel or inverter has already been used to claim STCs for the same project. There are 2 ways to claim the solar rebate Perth – either through the solar installer/company or online with the REC.Claiming the solar rebate through solar installer or company. The easiest way to claim solar rebate Perth WA is through the chosen solar installers or solar company. Some of them include the discounted solar rebate on the customer’s quote so that they have to pay less upfront. The company will later claim the rebate themselves. One can claim the value of rebate through the Solar company’s Industry Portal. The rebate will be deducted from the customer’s payment through the Solar company’s Customer Portal. The company does its job in few steps: They create a quote for customer. This quote is then uploaded to their portal for retailers. The customer will receive an email specifying whether their eligibility application is approved using the quote. Once the customer is eligible, installers will schedule the job within 120 days of rebate approval. They will carry out the installation and receive the customer’s payment minus the value of their rebate. The company will complete CES and submit payment request for the value of the customer rebate through their Solar Portal.  The installers will review the payment claim within 5 business days and approve if no further information is required. The deposit of funds can be expected in the nominated bank account after 10 business days of the payment being approved. Claiming the rebate online with REC One can also claim the solar rebate without depending on the installers, though the whole process is a bit strenuous. One has to register and fill out the online application through the REC website. Homeowners will then be given STCs which has to be registered and sold on market. It can be sold through the open market with prices subject to change or through the STC clearing house at a fixed price. When one is doing online, the easiest way is to have STC traders sell and register STCs for them. Either the owner can register and have the traders sell it for them, or even do all the process of registering and selling by themselves. A specialist STC broker can help one to get through these procedures. STC traders offer help regarding STC registration and selling. STC traders will buy unregistered STCs from home owners for a price that is little lower than the current STC spot price. They do so as they need to have some margin when they aggregate and sell the STCs themselves They also help in online and paper submissions, built-in solar panel validation, payment for selling the clients STCs to them within three business days payment after the audit. Some have their own STC assignment form template. Some of them even have online apps. Government rebate solar Perth have played a crucial role in the solar boom of Australia.

How long does the Tesla Powerwall last?

Tesla Powerwall is a rechargeable home battery system that stores energy from solar or the grid. The stored energy is made available on demand. It can power the home during the night or back up the home during a blackout or power outage. Powerwall is compact and easily integrates into a home. The Tesla Powerwall has a storage capacity of 13.5 kWh, a continuous power output of up to 9.6 kW, and three operating modes: Solar Self-Consumption, Backup Only, and Time-Based Control Mode To know how long a Tesla Powerwall last, we need to know about the power needs of a home and the power that Tesla Powerwall can provide. By adding up the power needs of each appliance, one can get the power needs of house. To determine the amount of power needed by a home, we have to decide on the appliances we plan to back up. Then we have to calculate the power usage of these appliances. Wattage of each individual appliances will help to calculate the collective power requirement for the entire home. To convert amps into kilowatts we need to follow a simple equation: Kilowatts = (amps x voltage) / 1,000 By comparing this number to the power rating of the Powerwall, we can understand how long a Tesla Powerwall will last. Each Powerwall can deliver up to 21 amps, and up to 6 Powerwall can be stacked together. The total number of Powerwall one install is a personal choice. It depends on:the amount of power one needthe amount of power one wants to storethe types of devices one wants to switch on during a grid outage. On an average, one Powerwall would run ten 100Watt light bulbs for 12 hours. An average home consumption is 28 kWh/day. One Powerwall will be able to power such a home for 12 hours. Two Powerwall will power it for 18 hours and three Powerwall powers it for 24 hours. As the number of Powerwall increase, the house will be more protected. One will get more hours of protection with an increase in the number of Powerwall installation. Pairing the Powerwall with a solar system is an ideal thing, as the Powerwall can be recharged indefinitely with the energy produced by solar panels. When paired with solar, Powerwall has the potential to run a home indefinitely. When it is a standalone grid, it won’t be able to recharge until the grid power resumes. Once the Tesla certified installers install the Powerwall, everything else is automatic. The battery automatically charges itself from the energy produced by solar panels and automatically turns itself off when necessary. Specifications of Tesla Powerwall Instantaneous Power Rating of Tesla Powerwall is 7.6 kW when the sun is shining and 5.6 kW with no sun. It is the power taken to start an appliance. For the initial starting some machines need a lot of power. After the initial start the power draw will drop considerably. It is essential to check whether the appliances at home need a surge requirement. Continuous Power of Tesla Powerwall is 5 kW. It is the power the battery can provide over a long period of time. It is the power needed to keep the appliances running after it has been started. This will tell you how many appliances can continue to run for an hour or more. The Usable Storage Capacity of Tesla Powerwall is 13.5kWh. It is a measurement of how much electricity a battery store. This means you can use either 13.5 kW for 1 hour, 1 kW for 13.5 hours, or something in between. A Tesla Powerwall helps to power a 3,500 W air source heat pump for just under 4 hours, a 300 W TV for 45 hours, a 200 W refrigerator for 67.5 hours, five 20 W light bulbs for 135 hours, a 25 W phone charger for 540 hours or a 6 W Wi-Fi router for 2,250 hours. If we run these items individually, the Powerwall will last for the above-mentioned hours. But if we use two or more of these items at the same time, it will reduce the number of hours the Powerwall will last. How long does a Powerwall last? An average home has an energy consumption of 25 kWh of energy per day. A small home may use as little as 10 kWh and a large home may use 40 kWh or more per day. Each Powerwall provides 13.5 kWh of usable energy for backup power. One can use the Tesla mobile app to monitor their usage and customize the energy usage for specific circumstances like maximizing protection during a power outage. Tesla app allows one to monitor and control their Powerwall remotely on iOS and Android. This app helps one to see how much energy is stored from solar, current power consumption, and the amount of energy your home is exporting back to the grid. The answer to the question how long a Powerwall lasts depends on the appliances that needs to be powered and the duration of time it needs to be charged. It would be ideal to figure out the essential electronics one would need in a blackout. By finding out the power draw of the required electronics, one can easily calculate the number of hours a Powerwall will last. If one is using only the essentials like Wi-Fi, phone, refrigerator, and some lights, they can expect the Powerwall to hold over for around 24 hours during a blackout. There will be a significant difference in the number of hours a Powerwall can power the house if we add other electronics, like TV or air conditioning system. An average homeowner typically draws 2 kilowatts maximum during an outage and an average of 750 to 1,000 watts during the course of the outage. This means a Powerwall will last for 12 to 15 hours. Tesla Powerwall 2 offers one of the best ratios for energy storage. A single Tesla Powerwall 2 stores 13.5 kWh, basically enough to […]
