Any time you are discussing a solar farm project it is very important understand the difference between alternating current (AC) and direct current (DC) voltage. Solar power nameplate voltage is designated as DC (direct current). Electric utility company line voltage is designated as AC (alternating current). In rare cases utility company line voltage can be designated as direct current.

Since solar power systems are specified in direct current, and utility company programs are in alternating current (AC), it is important to realize how to translate dc into AC (alternating current). The general rule of thumb is to multiply the total direct current (DC) watts by 0.85 to arrive at AC (alternating current) level.

In California there are many programs that solar farms can participate in. After much study, Commercial Solar Design has concluded that the two most effective solar farm sizes are three MW and 20 megawatt. California legislation provides solar farm projects up to 3MW AC (alternating current) with a guaranteed interconnection or a must-buy for investor-owned utility companies. Another program; a RAM (reverse auction mechanism) allows for solar farms up to 20 megawatts AC.

Whenever you are planning on a solar farm you must decide on whether to employ a fixed ground mount or single axis tracker solar panel array. Commercial solar design encourages single axis tracker designs because the increased expense of single-axis tracker is canceled out by the increased income generated. The solar farm investment community has an interest in maximizing development return on investment which single axis trackers provide.

One also needs to take into consideration acreage use regarding solar farms. A 1 MWp block AC (alternating current) using single axis trackers on flat property in Central California is going to be roughly 805 ft long by 392 ft wide. For those who include several MW blocks, spacing, service roads, setbacks together with other factors, 1MW alternating current (AC) uses up approx. 7 acres.

If you are thinking about a solar farm investment you ought to focus on acreage and shape to allow for either a 3MW or 20MW alternating current (AC) solar farm project. This equals either a twenty one acre or 140 acre parcel.

Another aspect to consider regards conditional use permitting (CUP). The majority of locations will not be appropriate for solar farm projects resulting from countless aspects including;

neighborhood objections, Williamson Act, acreage is blanketed with trees and shrubs and permit won't be issued for clear cutting, area is within a 100 yr floodplain, deficiency of a provision for solar farms in the general plan, not enough capacity on established electricity lines, far too remote to access the existing power lines, a community already saturated with solar power electrical power, not located in an IOU territory, and a lot of other issues. Commercial Solar Design concentrates on solar farm projects and can assist you evaluate if your solar farm project is realistic.

For those who think you've got a parcel suitable for solar farming, right now is an ideal time so you can get moving on designing your project. Having said that solar farms are definitely not inexpensive. A solid solar farm investment can certainly return 15% or over. There is actually a Federal government grant to cover 30% of the project's entire price tag. The balance is split between 35 percent equity position and 35 percent loans. Commercial Solar Design has crafted a very interesting program for landowners who were not able to offer 35% equity. Opportunities abound but you must proceed quickly to take advantage prior to when others fill the capacity allotted to solar farm developments.
