Solar Power & Panel Calculators

Solar power and panel calculator

Have you heard that solar power is helping people save money, and that harnessing energy from the sun is becoming more affordable with every passing year? If you're interested, read on to find out how much you can save by going solar …


The energy industry is not always layman friendly; the jargon can be intimidating, and there are many technical and financial factors that determine how solar pricing works. But there's no need to make it complicated: with the aid of Verengo’s specially designed online solar calculator you can find out how much you can save with a solar power system in less than a minute.


How Many Solar Panels Will I Need?


A typical solar panel is rated for about 250W. You can look up the peak sun hours for your area, but a good estimate for southern California is around five peak sun hours a day (this means that all the sunlight throughout the day, even the little bits in the mornings and evenings, is equivalent to the sun being out at full power for five hours). So, you can expect a single solar panel in southern California to produce:


250W x 5 sun hours/day x 365 days/ year = 465 kWh/year


If last year your home used 10,000 kWh, then you could expect to wipe out most of your bill with about 20 solar panels.


There are quite a few variables that a solar power calculator takes into account before it gives you an answer. Of course, the estimates you get are ballpark figures. Exact estimates can only be given by a qualified professional performing an audit on your property.


Here are a few other factors you should understand when going solar …


1. $/kWh rate (electrical billing energy rate): kWh stands for kilowatt hours, and means 1,000 watts (power) used over one hour. Cost per kilowatt hours ($/kWh) means the amount you pay per kilowatt hour. To calculate how much you are paying per kWh, just divide your monthly bill by your monthly usage. So if your last month's bill was $100, and you used 700 kWh, then you paid $0.14/kWh. Depending on where you live in the U.S., you are likely paying between 6 and 25 cents per kWh.

2. Utility metering: Includes all the types of metering agreement you have with your utility. Utility metering includes…

a.  Net-metering: refers to the billing method where you are credited for the electricity you feed back into the grid; a single meter measures both the out and inflow of electricity. Net-metering is one of the reasons why solar power is so popular, as it allows homeowners to sell excess power, and gain a return on investment.

b.  Gross-metering: refers to an arrangement where the entire electricity you produce is exported to the grid. Unlike net-metering, you are required to install two meters, one which measures energy export, and the other which takes care of all your energy consumption.

3. Solar Renewable Energy Credits: or SRECs, these are part of a state's Renewable Energy Portfolio (REP), which require increased production of power from renewable sources of energy, such as solar. A SREC is generated every time a solar power system generates 1 kWh of energy, and can be sold in an open market. Many companies buy SRECs from homeowners in order to meet their annual REP quota. Solar panel calculators take a state's REP laws into account before telling you how much savings you can expect.
