![]() ![]() This system is also successful in holiday homes, cabins and small offices. The off-grid solar systems are ideal for those living in caravans, camps and small houses. Similarly, you will be needing 24 solar panels of 250W if you are planning to install a 6kW solar system. Now divide the kW output by your panel’s efficiency to have an idea about the number of solar panels required for your off-grid solar system.Īn average UK household consumes 3kWh to 6kWh of energy on a daily basis.Īs a rough estimate, you will need 12 solar panels of 250W if you are installing a 3kW solar system. The result you will get is the kW output. For this, divide your daily kWh energy requirement by peak sun hours. When choosing your off-grid solar system, you will need to make a simple calculation. The size of your solar system depends on your daily energy requirement, the size of your roof and the average number of sun hours. ![]() How big should an off-grid solar system be? However, with that said, off-grid solar systems are still very useful for temporary or short-term use, especially if you intend on using them during the sunnier periods of the year e.g. You can potentially alleviate this problem by using solar battery storage that will allow you to store solar energy for use in the evenings.Įven so, during the UK winter, there is likely going to be times when there isn’t going to be enough sun exposure to fully charge your solar battery, so you will need a back-up system such as a traditional power generator or wind turbine. Two main reasons – firstly solar panels only generate energy in sunlight hours, so in the evenings and during the night there is no energy being generated by them. Realistically, no you can’t meet 100% of your energy demands for the entire year with solar in the UK.
