Slowly scrub the copper using your hands under running water to eliminate majority of the easily removed parts of the oxidized coating. Do not attempt to take off all the coating or scrub vigorously. The objective is to remove the regions that can easily be taken off. Do not damage the copper that stays below the oxidized layer. You can expect to continue getting power and energy from the sun for several decades without having to recharge batteries or keep purchasing new parts. Even though the energy may not always be readily available during cloudy days or at night, the availability is still there everyday. The solar energy supply will be available as long as the sun is existing. Does Solar Energy Reduce Cost Of Energy Consumption? Studies have shown that using certain solar energy systems do reduce the total cost of energy consumption that your home or work place might incur. If done right, you can actually lower your annual utility bill by as much as 80%, which is very significant, especially if you are trying to find ways to save some money. You can also invest in a ready-made design for added ease and convenience. Here are some more tips and tricks on how to begin. The Benefits If you choose to use solar panels, you can produce electricity that can power various applications. Off-grid living means residing in a location where the main electric utility grid does not service your home or office. The benefit of the system is the capacity to provide power away from the utility, as well as creating a measure of self independence. The complete stand-alone home solar system will usually have a couple of inverters to supply the AC house current needed to power very big loads like air conditioners. Here are just some of the possible advantages of using solar energy. Solar Hot Water Heater One of the more common uses of solar energy is for solar hot water heaters. Most homes in America actually have a hot water heater, which is probably why it accounts for about a quarter of the total energy consumption of a typical American home.
