How To Determine If Enough Sun For Solar Panels

However the power rating of panels can range from 250w to over 320w each based on size and brand.

How to determine if enough sun for solar panels.

Solar energy production is based on the panel size multiplied by the number of sun hours your roof receives. Solar panels are rated in watts just like your light bulbs except in the case of solar panels they produce rather than consume electricity. Simple online calculation tools will allow a homeowner to determine the average number of sun hours experienced in a particular location. Inversely with lesser sunlight hours more solar panels will be required.

To find your solar insolation simply click on insolation on horizontal surface average min max which is located in the second parameter parameters for sizing and pointing of solar panels and for solar thermal applications. By dividing this average hourly wattage requirement by the number of sunlight hours daily at the location you calculate the watts your panels need to produce every hour. Other online calculators can determine the angle at which a. Here s how to get a rough estimate.

In addition to our sun hour map we do also have additional insolation data available for other parts of the world to determine how many peak sun hours you have to go solar. Solar panel dimensions are on average about 3 by 5. If x kws are required to supply y kwhrs yr do you first divide y by the number of hrs yr to get x and then multiply this number by the fractional number of sunlight hours in a 24 hour period. You would need a bit more than 3 such panels to produce 1 kwh meaning 84 of these panels are needed to produce 28kw of energy during one peak sun hour.

Measure your available roof space. Email us at email protected and give us the location of your solar project. The solar system size your home needs will depend on your electricity consumption and the climate of your region. Figure out how many.

Solar panels which are typically made of crystalline silicon and use a system of lenses or mirrors to maximize the light that reaches them create an electric current when exposed to sunlight which is then used to produce electricity. You can use this data and the number of sun hours your town city gets to calculate how many solar panels you will need. Other factors can determine solar panel effectiveness such as roof direction shade or the climate where you live. Take a look at your electricity bill to see how many kilowatts on average your home uses each month.

Our solar professionals can help you determine the best placement for your panels. Solar power is created through the harnessing of energy from the sun. Solar panels are rated in kws. How much sun do solar panels need.

Using this figure you can select the panels required. How to determine size of solar panel needed.
