It is likely that you understand that solar electricity is renewable energy that is converted from the sun. Another name for solar electricity is photovoltaics or PV for short. You might be more familiar with this technology as you probably own a solar watch or solar calculator with PV cells. Watches and calculators are the simple applications of PV/Solar cells. Photovoltaic technology can be used for powering lights, residential structures, commercial structures, electric fences, water pumps and many other applications. The focus for this article will be on residential applications. There are viable reasons for using Solar Energy Systems for powering your home. Complete solar home systems save money on electrical expenses, saves energy, are a clean power source and it can come with tax credits. Residential PV systems can range in price depending on the power needs of the residence. The good news is that your electric bill will show a good return over the years since you are literally “selling” back energy to your power company. Solar Energy Systems involve having solar panels placed on the roof of your home where they can receive the most direct sunlight without obstruction. Photovoltaic systems (PV) are the most common systems found in residential applications. PV systems can be used to power your whole house. Professional installers set your system up to connect to the power grid which is how the energy is bought back (so to speak). The only time the power company energy kicks in is when the PV system is low on resources. A common myth is that solar panels do not work when it is overcast. The truth is that even on overcast days, PV systems can work even if it is limited. The savings can be dramatic. For instance, if you are currently paying $300 for electricity you are likely to see at least a 60% savings (more for some areas). Some people have reported paying under $30 for a month of electricity in their home with Solar Energy Systems. Utilizing high efficiency appliances and lighting will create even better results with PV systems. There are a few factors you will need to consider before installing a PV system for your home. 1) You will need to consider you energy needs. You should contact your local power company to find out the guidelines and requirements for grid connection. This simply means your PV system needs to be the right size to handle your energy needs. 2) The placement of you panels is important in getting the optimal use of a home solar system. Solar panels require direct sunlight to function. 3) Finally, you will need to consider your household budget. Even with rebates, Solar Energy Systems can be very expensive. They range from around $5000 to $40,000 depending on the size and your energy needs. One final note: Solar panels also keep your attic cooler in hot months which will reduce the need for pushing you’re A/C to its limits.
