Residential and Buisness Solar Energy Systems Either on ...

No matter how you slice it, electricity in any shape or form is uniformly useful no matter how it's fashioned. Presently there are 3 forms of solar power systems for residential or commercial installations. The decision of whether or not to use batteries is a huge aspect in the sort of system you come up with for using solar energy to power your residence or place of business. Grid-tie systems are a well-liked choice for home solar power systems. This type of system combines the use of solar panels, a DC-AC power inverter and the local utility's grid as a reserve. When your solar power system produces more electricity than what the demands are, you sell the additional power to your utility company. When the opposite is occurring (requiring more power than your solar power system can produce) you obtain the difference from the grid (Power Company). Many public utilities are instructed by law to purchase power fed into the grid from your . This law, however, is not unanimously accepted. Always make sure by checking with your local utility company before tying a solar power system to the grid. Not only are you required to obtain their permission, but even a technician will need to come by your home and go over your whole solar energy system. While grid connected systems use the electric utility grid as reserve power, battery backup systems employ a bank of to produce power during the nighttime hours, overcast days, and should the power grid fail. This type of system is more complicated, and quite a bit more exclusive than a grid tie system due to the extra controls and batteries needed. A battery-backup system requires a different type of in order to control the different type electrical connections to the local utility power grid and the battery bank. The difference between using deep cycle batteries as your backup power supply and using the power grid, is the extra cost and the ability to retain power in the home when the grid has failed. The cost of batteries will differ depending on the total size of your power system and the length of time you would like as a reserve. Typically, a three day supply of power is what most would need in the event of a power outage. A bank of batteries can cost anywhere between several hundred dollars to many thousands, depending on their type and storage capacity. If you are not comfortable in choosing which batteries to use, you need to go to a professional that works in these areas on a daily basis. It would be entirely possible to power your entire home's total energy requirements off of deep cycle batteries, however , sizing your battery bank to handle only those items deemed essential to survival would keep your total system costs down to a minimum.
