Faq's About Solar Power
1. Q. I live in an area where we get a lot of cloudy days. Is solar power for my home really worthwhile exploring?
A. Yes. While you may need more photovoltaic (PV) panels, or a somewhat different configuration, solar energy can be captured nearly everywhere in the world and used to either supply or supplement existing power needs.
2. Q. How affordable is solar power?
A. While still a little higher system cost than fossil fuel (coal, gas, oil) in many areas, once you factor in the incentives like tax credits, (federal and state), rebates, net metering, and the upward march of fossil fuel costs, the question may turn itself into one that asks "Who can afford not to have solar power?"
3. Q. What is the difference between a solar hot water system and a solar power system?
A. A solar power system consists of an array of photovoltaic cells, or some other solar collection method like parabolic troughs, that gathers the sun's energy, then converts it into electricity that you use and store for heating, cooling, lights and appliances...like your own little mini power plant. A solar hot water system is basically just a radiant hot water storage tank that uses the sun to heat the water you use in your home.
4. Q. What maintenance do solar power systems require?
A. No. Solar systems require little or no maintenance other than keeping your panels or other collection devices free of debris, heavy snow or leaves.
5. Q. What about financing for solar power systems?
A. Financing is very available. Like any other home improvement project, solar system installation will generally qualify for a home equity loan if your credit is good.
6. Q. Will I need a solar professional to assist me?
A. This really depends on your expertise and comfort level. Solar professionals can help you avoid the pitfalls of a beginner, and usually know who the best installers are in the area, both of which could save you big bucks. But if you don't mind doing the research, and are comfortable with your own knowledge base, you can also do it on your own.
7. Q. Should I get multiple bids?
A. Just like any other project, having more than one bidder can help you determine not only the best price, but present you with different installation choices. Before you decide on the final plan, get as many ideas as possible, set realistic expectations before you start the work, and once you start, stick as close to the plan as possible. Doing so can keep you on budget...and on plan for completion.
8. Q. Am I going to have to have a lot of roof space for a photovoltaic (PV) system?
A. If you're looking at a 1000 watt system, you'll need between 100-200 square feet of area (an average bedroom in size), so once you determine how many watts you'll need for your system, you can calculate how much room you'll need.
9. Q. Can you explain net metering?
A. Usually, it means money in your pocket. Your local utility (in an on-the-grid system) installs an additional meter to track the energy you produce from your system and your usage throughout the day. When you produce more than you use, that excess goes back into the utility power grid to provide energy for others, and your utility account gets a credit, or an offset against any power you may use from the utility grid.
10. Q. Am I really going to be making a difference in global warming if I move to a solar power system?
A. Everyone who quits using coal, gas or oil to provide power to their home makes a difference. Since the average American produces 53,000 pounds of carbon dioxide a year, everything each individual does to reduce their carbon footprint makes a difference. Every person who converts to solar energy to fill their power needs sets an example for their neighbors...or any stranger walking by. Yes. One person can make a difference.
