Peek Charging Time Solar Panel Per State

The solar charge times above assume a 25 degree celsius day with the panel pointed directly at the sun.

Peek charging time solar panel per state.

For the sake of example if you are getting 5 hours of direct sunlight per day in a sunny state like california you can calculate your solar panel output this way. Solar pcu is a device through which you can directly connect your solar panel and your battery charging will start without any solar charge controller because it has a inbuild charge controller. And if you want to continue with your existing inverter then you can buy smarten 24v 50amp. When deciding to switch to solar you ll want to know how many peak sun hours you typically get in your geographic area to give you an accurate estimate of the production of your system.

I put together the following battery state of charge chart which indicates the state of charge percent as it relates to battery voltage or specific gravity. But first a few important notes and caveats. How much energy does a solar panel produce. A peak sun hour is the equivalent of the sun shining at an intensity for 1 000 kw per square meter for one hour expressed as 1 kwh m.

Putting it all together. By comparison states with fewer peak sunlight hours can be just as ideal for solar panels but will require more efficient solar equipment. 5 hours x 290 watts an example wattage of a premium solar panel 1 450 watts hours or roughly 1 5 kilowatt hours kwh. Environmental factors will likely increase charge time.

Thus the output for each solar panel in your array would. The low angle of the sun at sunrise and sunset means that the atmosphere filters the sunlight more and results in less energy being delivered to the earth s surface. Three tips for solar shoppers 1. This number is calculated for a fixed solar panel.

Average peak sun hours vary greatly across the country. If you know the average daily peak sun hours for your location you can calculate the kwh your solar panels will make on a daily monthly and yearly basis. Each peak sun hour is defined as one hour when the intensity of sunlight solar irradiance reaches an average of 1 000 watts of energy per square meter roughly 10 5 feet. How much sunlight intensity you get in your state or even the given sun hours per day by zip code can make a dramatic difference and directly.

When planning and trying to understand what impact solar panels can have on your electricity bill it helps to use an average number. Using a yearly average there are 5 38 daily peak sun hours across the state of california. Just as in the chart above peak sun hours are. 10 watt 18 volt solar panel charging a 12v 10 amp hour lead acid battery 120 wh from 50 full to full time 60wh x 2 10 watts 12 hours.

In a state with strong peak sunlight a panel with lower efficiency will likely do the trick. Peak solar radiation occurs at solar noon when the sun is highest in the sky. Voltages and specific gravity are listed for a 6 volt or 12 volt battery and battery banks of 24 and 48 volts. Some quick rules for estimation.
