Calculate How Many Solar Power Panels Are Needed for Whole House

Solar energy is the way to the future of energy development. Fully renewable, sustainable and fairly reliable, solar energy is becoming more of reasonable power source and less enthusiasm. If you get in thinking on this sustainable resource for energy, you must first have to do some significant planning.

You need to know exactly how much equipment you need to buy in order to maintain your current state of life and that has to do with the calculation of number of solar panels you will need. There are numerous computer on the Internet available on Solar Panel calculations, however, these simple steps can manually calculate today. Determine the number of kilowatt hours or kWh budget used on typical day.

This can be done by examining your electric bill and dividing your monthly kWh measured by number of days in billing cycle. For more accurate estimate, look at your year-end kWh usage and divide by 365. Calculate amount of energy that can be stored in your battery bank.

Determine size of battery bank required with this formula total load in watts X days of backup storage or system voltage X efficiency after system losses . As example, average household uses 29 kWh per day, and let’s say you want two days of backup storage with 24-volt batteries 29,000 X 2 or 24 X 0.80 = 3,020.83 amp hours at 24 volts. Most 24-volt batteries will sustain around 5 amp hours, and since you will also be charging your system constantly with solar panels, you can assume that there will only be 5 percent draw on your batteries. Thus, 3,020.83 or 5 = 604 X .05 = 30.2 or bank of 31 24-volt batteries.

Calculate number of solar panels needed for your battery bank. Divide total amp hours per day 3,020 in our example by average sun hours per day based on solar insolation chart, 4.2 in our example to get total array amps needed. Determine peak amps produced by solar module you are looking at purchasing divide module’s wattage by peak power point voltage, 17 in our example .

Divide total array amps by peak mps and round to highest whole number 43 in our example . This gives you total solar panels needed for your home application based on your energy requirements and solar panels you are looking at purchasing.
