Average Solar Panel Output Uk
In average uk weather conditions you can expect one kilowatt of panels to generate between 700 and 900 units kilowatt hours kwh of electricity per year.
Average solar panel output uk. Most residential solar panels on today s market are rated to produce between 250 and 400 watts each per hour. The higher the wattage of a solar panel the more electricity it can produce under the same conditions. Domestic solar pv systems range in size from 1kw to 5kw although a typical domestic solar pv system is around 3 5kw with 12 panels. Generally speaking a 3kw or 4kw solar panel array will be able to produce enough energy to power a home containing a family of four or five people.
On average a domestic solar panel has a power output of around 265 watts although it can range anywhere from as little as 225 watts to more than 350 watts. So a 5 kilowatt system could be composed of 20 solar panels each at 250 watts a piece. A 4 kw solar panel system on an average sized house in yorkshire can produce around 2 850 kwh of electricity in a year in ideal conditions. However just like a solar panel you can t assume your solar system will be working at 100 efficiency at all times.
Solar panels usually range in wattage output from around 250 watts to 400 watts but some panels exceed the 400 watt mark. Each is about 5 of demand. Where you live will be a factor for example cornwall receives 30 more solar energy than northern scotland. A 2kw or 3kw array on the other hand will be able to supply enough energy to power a smaller home.
These costs are estimated and based on industry averages. As an average figure a solar panel system should produce 2 35 kwh per kwp per day. To calculate how much electricity a solar panel will produce in a day you simply have to multiply its wattage by the number of sunlight hours. The solar panel with the highest watt is the sunpower e series a commercial solar panel line.
According to smarter business the average uk household uses about 3 100 kwh of electricity each year which equates to between 12 and 16 panels. 9 4kwh x 365 3 431kwh per annum. Uk solar pv installed capacity at the end of 2017 was 12 8 gw representing a 3 4 share of total electricity generation. 2 35 x 4 9 4kwh on an average day.
The top panel in the e series comes out at a whopping 435 watts. Domestic solar panel systems typically have a capacity of between 1 kw and 4 kw. In the summer half year from april to september 2016 uk solar panels produced more electricity 6 964 gwh than did coal power 6 342 gwh. About 1 6m x 0 9m and around 5cm thick.
Every 1kw system can produce around 850kw units per year. According to the energy saving trust over the course of a year a typical 3 bed house uses a little over 3 000 kw units. A 4kw system will on average generate around 3 400kwh of electricity per year. Most solar panels come in one standard size.
