Our solar rig uses state-of-the-art panels, control and storage technology:
- 1000W (1KW) of solar panels. Our panels are board-mounted semi-flexible monocrystalline units, arranged in two arrays. We chose these for their lightweight characteristics, and low-light performance. Panels are mounted at 35°, optimised for summer in southern UK.
- MPPT Victron charge controller, which carefully optimises and stores the power from the panels.
- 1.2KW Victron pure sine-wave inverter to produce protected mains output through standard 3-pin and 16A leisure (weather-proof caravan hookup) sockets.
- about 5KWhr of stored power (200AH Batteries at 24v).
The system is carefully monitored throughout events with data broadcast via Bluetooth to an App. This helps ensure steady production and storage of power for night times when demand generally peaks.
How much power can we provide?
We can provide 240V mains power for loads of up to about 800W. Technically we can go way beyond this but we include a 50% safety margin to ensure we can cope with any peaks. 800W is a massive sound system, or enough to power 80 domestic sized LED lightbulbs (equivalent to a whopping 6KW of light from normal tungsten lightbulbs!)
We can also provide 12V up to 150W. This is enough to power many strings of 12 V LED lights, and a small stage sound system.
Our batteries store enough energy to power 50 10W LED lightbulbs for about 7 hours continuously, i.e. all night in mid-summer. With reasonable sunshine we should be able to fully recharge each day.
240V outlets are protected with a 30mA RCD ‘trip switch’. The Rig is also earthed to a copper rod hammered into the ground wherever we go.
Where we are supplying 240V mains voltage to events, we are responsible for the power up to the sockets, which we place in a lockable, weatherproof plastic box. Thereafter, access to, safety and use of the power is the responsibility of the user.
Our solar rig is completely bespoke, designed and built by Dr Matt Little of Renewable Energy Innovation in Nottingham.
