Go Greener Tips

A lot of homeowners are serious about installing a solar power kit on their home to take advantage of the free energy, tax incentives, and clear conscience that they offer. But before you go out and purchase a system or call an installer, you should think about where it’ll installed. This article will assist you to decide. These are the questions you should be asking yourself:

1. Where is the very best access to sunshine? Solar panels within the Northern Hemisphere ought to face south, or as close to south as possible. Many people mechanically assume that the array ought to go on the roof. But in case your roof does not have a south-facing section, you could have to think about putting it on the ground or on an out-building resembling a shed or a garage.

2. How a lot shade will there be in this place? Shading will kill your panels’ efficiency quicker than something else. You’ll have to consider your trees, your neighbors’ trees, vents, air con units, and every other obstructions that could shade your panels. And remember that the suns angle changes not solely over the course of a day, but over the course of a year. The best instrument to determine what kind of shading you will experience year-round is a Solar Pathfinder, which may be ordered at most online solar stores.

3. Will shading be an issue 10, 20, or 30 years from now? Solar panels can last anywhere from 20 to 50 years. So the system you put in today will probably be there for a protracted time. Take a minute to consider how tall bushes and trees shall be 30 years from now. Can you trim them? Will you need to?

4. Will I need to access them to take away snow and/or clear them? Homeowners in areas vulnerable to snow, soiled rain, or heavy dust might need to often clean the panels. If they’re on a roof this can be dangerous and inconvenient. Usually solar panels are positioned at an angle close to 45 degrees, so they have a tendency to “clean” themselves. Often cleaning simply involves a backyard hose or a long handled broom.

5. How a lot room do I want for the system? The most typical panels take about one sq. foot of space for every 10 watts they produce. For example, if you decided that you wanted about 3,000 watts for your home, you’d divide 3,000 W by 10, for 300 sq.ft. This is about 17 by 17 ft square. You’ll also need a few 3′ by 3′ space on the wall near your electrical meter to put in the vital components. If you’re considering a battery financial institution for the system, you will need an area in regards to the size and shape of a large chest freezer to store them.

6. Will I be capable to adjust them because the sun angle changes? As the seasons change, so does the angle of the sun. The optimal angle for the panels is at a 90-degree angle to the sun. The extra adjustable the panels are, the more energy they’ll produce. Tracking programs will follow the sun across the sky at any angle. For these not wanting to vary the angle of their system, the system should be place at an angle equal to their latitude. So somebody living in Spokane, Washington, which is at 48 degrees latitude, would place their panels at forty eight degrees from horizontal.

7. Is it near my energy needs? Solar units produce direct current (DC) power, which is infamous for line loss, which suggests the farther is has to travel, the more energy it loses. The strategy to offset this loss is to use larger, and extra expensive, wire to move this energy. So, the farther away from the home equals larger installation cost.

8. How will this affect my neighbors? Solar arrays clearly collect sunlight, and therefore cast a shadow. Will this shade your neighbor’s award winning tomatoes? Will the panels block their satellite tv for pc dish? Installing photo voltaic is a minimum of partially about being a superb citizen, both regionally and globally.

9. What are the local zoning codes and covenants? Although most municipalities are “greening” their codes to permit for renewable energy systems, all of them have restrictions on peak and proximity to property lines that systems might be built. A visit to the local permitting office is normally worthwhile. Try to talk to somebody with essentially the most authority on the matter (usually a Planning Director or Compliance Officer) so that you avoid the entire ‘but the lady on the counter stated it was ok!’ conversation down the road.

10. Can I do that myself? With correct planning and education, the kits supplied today make it simpler than ever for do-it-yourself homeowners to put in solar. However, you should all the time obtain the right permits (this course of will inform if you’re even allowed to place it up yourself) before you start the work. You ought to also all the time have a licensed and insured (and ideally Master) Electrician do the final connections and testing in your system. And remember, working in excessive places could be dangerous, so all the time use correct safety equipment.
