Few people remember that President Jimmy Carter had solar panels installed on the roof of the White House and that President Reagan removed them, when he took office. Thus began the "alternative energy debate." This week's Renovator's Weekly list answers some common questions about solar energy systems for homes.

Is Solar Power Affordable?

While solar power is not "cheap," the consensus of those who follow climate change is that the long-term environmental costs of current fossil fuel energy use are both difficult and profound to measure. The Global Climate Risk 2010 report issued by Germanwatch estimates that, since 1990, extreme weather events related to climate change have caused approximately $1.7 trillion in damage worldwide.

From Copenhagen to Kyoto, the message is clear: We can't afford to wait for governments to agree. Individuals must begin taking the steps necessary to clean up our environment and reverse humanity's polluting impact.

Thus, we need "alternative" energy to beome mainstream. That's one reason the federal government is offering a tax rebate of up to 30% of the cost for installation of solar power energy systems. This rebate applies to solar water heater systems and photovoltaic (PV) panels.

Should You Lease or Buy Solar Panels?

Based in Foster City, California, Solar City allows qualified homeowners to lease solar power home energy systems with no money up front. You pay the lease and a lower power bill, as you go. You can even lock in your solar power bill rates. A warranty spans the life of the lease, in case repairs are needed. Check with solar energy providers in your region for similar arrangements.

While you do save money in the long-term, if you buy your own solar panels, leasing solar panels allows homeowners to try out solar energy before committing competely, and to begin lowering their carbon footprint immediately.

What Is the Best Way to Install Solar Panels?

Find a licensed contractor who specializes in solar panel energy systems installation. This is not a do-it-yourself project.

Is There Enough Sunshine In Your Region to Power Your House With Solar Panels?

If you live in the Southwestern United States, you won''t have much trouble answering this question. However, for New England, the Midwest, and Pacific Northwest, the answer seems less intuitive. Consider a solar-powered hot water heater, wind and geothermal energy. Consult alternative energy providers in your area for more details.
