Solar Panels - Cost?

Postby alice915 » Fri Aug 14, 2015 3:53 am

I want to know as to how much it costs to install the panels if you buy them (not lease) and whats your break even point, how much you save a month approximately?

So lets just use for example a single family home in the SFV area lets say 3-4 bedrooms, 1,800 sq ft or so.

Let me know any figures you may have.

Thanks in advance!

These programs are changing all the time, so it's best to check the specifics of the lease program you are evaluating with each solar company you are speaking with since the mechanics of lease program you are describing also exists. My lease was for the solar panels themselves - similar to a car lease with a down payment then an interest rate on a stream of payments based on our credit/income. We chose that because it was less $ out of pocket up front, and SolarCity guaranteed & warrantied & monitored our panels for 20-yrs (at the time they'd only provide those services for 5 years if you purchased the system).

My understanding is also that in LA, everybody is still required to be connected to the grid (the larger electric utility framework serving the whole area) - so even if you generate your own electricity on a lease or owning it, you pay $20ish/month to be connected no matter what. Thus your meter spins backwards generating electricity for the grid when you generate excess, or conversely at night you can use the power from the grid. I think there are other utility districts where you can be 'off grid' (like the in desert, mountains, etc) where it's harder to connect so your solar system would truly be 'stand alone' there.

Although solar power conversion efficiency is relatively low, only 12% to 16%, no one in the world can break through this figure. However, it is widely used in many fields, such as space, communication, military, transportation, urban construction, civil facilities and so on, without pollution, location, convenient maintenance, long service life and so on. Compared with other new energy sources, solar energy has more advantages in terms of resource potential and durability. Taking power generation as an example, if the cost of coal-fired power generation is 1, the cost of small hydropower generation is about 1.2 times that of coal, 1.5 times as high as coal, 1.7 times the cost of wind power generation, and 11-18 times the photovoltaic power for coal. Of course, it's 10 times the wind power generation! Only the former stage 1000W photovoltaic system, under the condition that the price of silicon chip is not more than 50 yuan per watt, the market price of kW system assembly is 150 thousand yuan, and there is also a minimum of 7500 yuan, but the efficiency is low. The original goods are not less than 100 thousand yuan per kilowatt.
