Check for government certification on any solar panel you are considering buying. Consider this tip a must. The government's seal of approval lets you know that these panels are deemed quality and efficient. Plus, some of the financial benefits of using solar panels (tax credits, etc.) rely on using certified panels.
See how to test your solar panel for open voltage and current reading. Results will vary depending on sun strength, time of day, angle of light and temperature.
The best time to incorporate solar power into the design of a home or building is in the initial construction. Windows are best facing south to let maximum sunlight (hence greenhouse heat) in during the winter. Likewise, avoid windows facing directly into the summertime sun to keep things cooler, so less power is needed for fans or air conditioning. The maximum roof space, however, should always get sunlight exposure.
Check with your local power company as to whether they have a program to buy excess electricity collected by your solar panels. Some utility companies will give homeowners credits to apply to any energy provided to them. These programs are becoming more available as more and more people install solar panels on their home.
