The increased popularity of solar DIY panels in homes and commercial buildings worldwide would be hard to miss these days. Even for those who don't keep up with current events, it's easy to notice solar panels that power road signs, office buildings, and homes. In the U.S., tax credits and other incentives have served to increase the popularity of solar DIY panels. Pre-made solar panels don't come cheap. A system designed to power your whole home can cost anywhere from $7,000 to $100,000 installed. Fortunately in the U.S., federal tax credits and local incentives can cut these costs dramatically - sometimes as much as 50%. Costs can be further cut by installing panels yourself, and can be cut even more by making solar DIY panels.
