For the time being, solar power for homes is still relatively expensive. At $800 for a 170 watt panel, it would take over $10,000 to power the normal off grid home with solar energy. That is a lot of money for many people.
There is a better alternative. You can use solar energy by building a solar system via a Do It Yourself (DIY) approach. How is it done? This article will present some information as a guide to solar power utilization in residential unit.
Do build a home solar power system is not very difficult. Firstly, you have to be good with hand tools and have ample working space. You will also need to commit a few weekends to get the job done. A
home solar system consists of a large solar array to harness the sun energy. A solar array is made from small solar cells or Photovoltaic lined in series.
Solar cells have the ability to generate electric current when exposed to sun light. To capture the maximum sun light, solar array is usually built on the roof. Electric current produced by the cells can be stored in deep cycle batteries bank. The size of the solar array and the amount of batteries required for the system will depend on your home energy demand.
Before you start building your DIY solar power system, you need to do a proper energy audit for your household. You have to know the power requirement of all your electrical appliances. The auditing process is quite easy. To make sure you do the job right, it is a good idea to get a home solar power guide book.
