Thinking of installing solar panels? how many solar panels do I need The very first step is to estimate how many solar electric (or photovoltaic, PV) panels you'll need to generate the electricity you need. Step 1 - Just How Much Electricity do You Use? You will should discover how much energy your family currently consumes or plans to consume. One way to complete this is to adopt an inventory of the wattage requirements coming from all of the electrical equipment and fittings. Multiply the whole wattage requirement through the total variety of hours you use your electrical equipment.. A easier alternative is to make use of copies of your electric power bills to the past 12 months. Add the number of kilowatts used each month, or simply just use one of the most recent cumulative year end total. If you don't have copies of your bills, your utility company will often provide you with all the figures, but may charge you.. Divide total kilowatts used throughout the year by 365 to acquire average daily kilowatts used. Step 2 - Convert Kilowatts To Watts Then to transform kilowatts into watts, divide the daily kilowatts employed by 1,000. Now you might have the average quantity of watts your household uses daily. Step 3 - Simply How Much Electricity Are You Wanting From Solar? Multiply the daily watts used because of your household by the number of total electricity that you need to replace with solar. So, if you want to replace 25% of your electrical needs with solar, then multiply by 0.25. If you want to be able to supply 100%, in order that you employ grid electricity only for backup, then multiply by 1.00. This number is the average daily total watts of electricity to would like your solar energy system to deliver. Step 4 - Adjust For Solar Insolation For A Site Divide through the solar insolation value. You will have to get the to get the "solar insolation values" for your geographical location. The "solar insolation value" is really a measure with the amount of sunlight that truly reaches your site. The angles from the Sun's rays hitting Seattle at noon are very different off their angles hitting San Diego at noon. Accordingly, the Sun delivers different amounts of solar energy at each location. To find insolation values for your United States, make usage of the maps by the National Renewable Energy Laboratory.Look for that PV Solar Radiation Static Maps that demonstrate monthly averages. Using a yearly average will present you with incorrect values for your summer and winter extreme temperatures.) For other countries, look for "solar maps"," insolation maps", or "solar radiation maps" + the country's name. Use the minimum monthly insolation value - December's for your United States. Your estimate will then be based for the least amount from the Sun's energy available at the location. Now divide the average daily total watts of electricity you desire your solar energy system to supply (the number from step 1), with the solar insolation value for the site. This gives a preliminary estimate from the number of watts of electricity your solar panels will should generate. Step 5 - Adjust For System Inefficiencies Now multiply the quantity of watts through the last step (step 2) by 120%, or (1.2). This will give which you 20% allowance for power loss which will occur since the electricity out of your solar panels makes its way with the system. No product is 100% efficient. This number can be your final estimate from the total amount of energy in watts that the solar electric system will must deliver. Step 6 - Adjust For The Solar Panel Specs Now divide one last wattage requirements (from step 3) with the peak wattage from the solar panel you plan to buy. You will get this number from the solar panel manufacturer. Should you are shopping online, seek out a spec labeled "maximum power" or something like that similar, and expressed in watts. Step 7 - round Up For Total Round the effect to the next highest number (for example, round 5.3 to 6 solar panels) to have the approximate variety of solar panels you'll have to buy.
