Check if you have enough space Take a look at your electricity bill to see how many kilowatts on average your home uses each month. The average solar panel measures about 17.6 square feet and produces 265 watts under direct sunlight per day, which is equivalent to 15 watts per square foot. The most important factor in choosing solar panels is knowing how much sunlight you receive. But you don't have to live in a completely sunny location for solar panels to work for you.
Solar panels work well in most climates. Find out if your home is ready for solar energy and compare offers from a list of local, trusted installers online. Google has created the Project Sunroof website, which will allow you to enter your address and get an instant report on your solar potential or how much sunlight your home is projected to receive based on local weather data. Solar energy can power all of your home's electricity needs, whether you own or rent them, including lighting, heating, computers, and appliances.
If you end up needing a new roof after installing the panels, you'll need to ask a solar specialist to remove the entire system and then reinstall it after rebuilding the roof. Applications for a reduction in solar taxes require disclosure of eligible solar power generation system expenses. Solar panels work best with strong and durable roofing materials, such as composite or asphalt shingles, concrete shingles, or metal for standing joints. Solar panels should be installed on roofs that are in good condition and that will not need to be replaced in the near future.
On a typical cloudy day, solar panels produce 25% of their normal production, while on a very cloudy day they produce 10% of normal production. A solar energy consultant will calculate the amount of energy your system will produce so you can see potential savings before deciding to use solar energy. To see if your home is a good candidate for solar energy, try a solar panel suitability tester, such as Google's Project Sunroof. Then schedule an appointment for a solar consultation with an expert who will visit your home to inspect its orientation (south-facing solar panels capture more energy), the angle of the roof, and the shade of the trees to see if your roof will receive enough sunlight to meet your family's energy needs.
SunPower solar energy consultations are free and you can learn a lot about your home and the best energy options. The optimal angle for installing solar panels is a 30 degree slope, although this may vary depending on latitude. It is more difficult to install solar panels on tile roofs, because the shingles are brittle and because the installation can damage the waterproofing barrier under the shingles.
