What size solar system do i need uk.

In the uk 12 solar panels are needed for a 3kw solar installation and 24 panels for a 6kw installation. We want to help you get the system that s right for you. 33 kwh 6 1 sun hours x 1 15 efficiency factor 6 2 kw dc solar system size required using the example above with a 6 2 kw dc system you can multiply this number by 1 000 to confirm that you need 6 200 watts of solar panels. And for highly efficient panels it reaches down to 448 sq ft.

To get these numbers we used high and low panel production ratios to calculate how many solar panels are needed on average. The number of solar panels is dependant on your energy consumption sun hours and roof size. To cover that energy need. They re usually about 2 metres tall and 1 metre wide with a thickness of 3 5cm.

For a 10 kw system size using low efficiency panels your system will occupy around 612 sq ft. However the wattage output w of the panels will likely vary between 250w and 360w for a more efficient module. This is a very general system size estimation. In this case each panel takes up roughly 1 239 1 44 square meters of space.

As a guide you ll need 4 x 250w panels or 3 x 330w for every 1kw of your solar system. For any given energy production target you need fewer panels if their individual wattage is higher. Other factors such as peak load shade location available panel space and seasonal use need to be taken into account. What size solar charger do i need.

Solar panel insurance guide. But if you used medium efficiency panels that number lowers to 508 sq ft. You ll need 6 2 kw dc according to the formula. Panel specifications the power rating of panels varies depending on the model and manufacturer but most range from 250 watts to 330 watts.

When roof size is limited efficient panels with a high wattage can make the system more compact. For a 19 72 square meter roof you could install a maximum of 12 15 solar panels. Do expect them to trickle charge a healthy battery. For the most accurate and personalized off grid system size calculation call our solar experts at 1 800 472 1142.

However some manufacturers have recognised the need for compact panels which are ideal for households with small roofs. The typical homeowner will need 28 34 solar panels to cover 100 of their energy usage dependent on location and roof size. If you live in a very sunny area then you can hook up a more powerful solar charger for the day come back and find that the battery is topped up. The average solar panel is 78 74 x 157 48 centimeters which you can use to roughly calculate how many panels your roof will hold.
