Most solar modules have a 20-25 year output warranty, but should last even longer since there are no moving parts. The average life of a battery depends on several factors; grade of battery (inexpensive golf cart to expensive industrial 2V cells), depth of discharge, number of cycles, temperature of battery and maintenance. To get the most out of your batteries, you should try to maintain them as close to 75° F as is practical and keep a good state of charge on your batteries while minimizing the number of deep discharge cycles. Also, an equalization charge (controlled overcharge) should be performed every 3 months or so followed by a replenishment of electrolytes. Electrolytes can be distilled water or gel based, depending on battery type.

  • How much maintenance does a PV system require? 
    Not much beyond equalization and maintenance of the batteries mentioned previously. Also, the tilt angle of the array can be adjusted seasonally to maximize the solar array's energy output.

Photovoltaic can power just about any electrical load. However, air conditioning and electric heating elements (cook stove, water heater or furnace) use large amounts of electricity which drives the system cost beyond the average homeowner's means.  More Info -->

Yes and no. Each state, county and even local utility company does things differently in regard to buying back power. Some states have passed a net metering bill which states that you can sell power back to the utility grid at the same rate that you purchase it. Some power companies only buy back power until you "break even". States and utility companies that have not adopted this net metering policy will only buy back power from the consumer at a wholesale level which may only be 2-3¢ per kWh. Check with your local utility company to see which policy they have adopted. Either way, it would require a very large solar array to make an appreciable amount of money by selling power back to the utility grid.

Currently the Federal Government has passed a production tax credit of $0.017 for each kilowatt hour sold. At least 36 states offer incentives for Alternative Energy. Check with your states Department of Energy and see if these incentive apply to you. A good website to visit to learn about state incentives is More Info -->

First think of Solar Systems as your bank account:

  • Deposits = Panels 
  • Payments (Checks) = Appliances (TV, Refrigerator, Lights etc.).
  • Balance = Battery Bank

Renewable energy can be cost effective right now in the right application. For cabins and homes the first step is to make sure that you have the most energy efficient appliances available. This will lower your cost of the renewable energy system and give a quicker payback.

  • What size system should I have installed?
    For most residential and small offices, a 1 kilowatt to 3 KW system should add some real value. For smaller homes and limited roof space, a 250 or 600 watt system can be installed. A rough calculation is that 100 watts of AC peak power require 12 square feet of roof space - or 1 KW requires 120 square feet.

  • What size system do I need?

    It is very easy to calculate your system size. First, you need to obtain your daily power consumption average in units of kilowatt hours (kWh). This power consumption will be listed on your electric bill. Use the instructions below to make this calculation if this average daily power consumption is not provided by your utility company.

    Total kilowatt hours (kWh) used: (a)

    Number of days in billing cycle: (b)

    Average daily kilowatt hours (kWh) used: (a) / (b)=

    The number calculated for your Average daily kWh used can now be used in the exact system size can be calculated by our engineers. support@oksolar.com

What will my solar electric system cost?

A rough calculation is that, the installed cost for small systems (less than 5 kW) without batteries runs between $ 8 and $13 per Watt. For larger systems (over 10 kW) without batteries the installed cost is between $5 to $10 per Watt. For a small battery pack $1.75 per Watt should be added. For a large battery pack $3.50 or more should be added.
