I went to Bimbles today to buy a solar panel for my campervan. I had a rough idea what I wanted but they ran through my power requirements to make sure that I bought the right panel for the job. There was no hard sell, just completely honest advice. The products are great and the prices are too. I can't recommended these guys enough and will definitely be back again

(10A is the utilisation capability for ELWA, there is no problem with using bigger PV panels, the Isc above 10A is dissipated. You can estimate the system by using ELWA dimensioning sheet link above, only red conditions should be avoided)
Use solar power directly for domestic water heating.
ELWA is a 2 kW photovoltaic water heating device. Direct current from photovoltaic modules is transferred directly to the built-in heating element and immediately converted into heat without loss. The built-in MPP Tracker ensures that the PV generator is always operated at the optimum operating point (similar to a PV inverter). For operation, no connection to the mains is required as the unit is powered by the PV generator (pure off-grid operation). The desired DHW temperature is set with a rotary knob, LED displays inform about the current device status.
Always warm water, even during bad weather.
Due to the patented boost-backup function, hot water supply can be guaranteed even during bad weather. This makes it possible to completely switch off the conventional heating system in summer. This also increases its lifespan.
For commissioning the boost-backup function, ELWA can be easily connected to a mains socket. There is no feed-in into the grid, so it does not need a metering point like a grid-connected PV system.
Advantages
Easier and cheaper than thermal solar systems
No grid operator approval required
You save yourself tedious administrative work, because ELWA does not feed electricity into the grid. Especially in multi-storey apartment projects, the approval can take several months for grid-connected PV systems.
Easiest installation with "cables instead of pipes", less valuable copper, no maintenance costs.
Stratification-heating possible with 2 devices.
Even works in case of power failure.
Boost-backup optionally usable.
No anti-freezing liquid necessary
Cables have almost no energy loss compared to pipes

Protect your off-grid or grid tied PV system from unexpected string faults using Mersen’s HelioProtection® fuse line
Developed specifically for the protection of PV string wiring for 1000VDC industrial rooftop and utility scale photovoltaic systems. Its robust construction makes it ideal for continuous temperature and current cycling withstand adding to system longevity. The 1000VDC rated fuse is designed for low minimum breaking capacity capabilities of 1.35 times the fuse rated current value, allows for safe circuit interruption under typical low fault current conditions produced by PV arrays.
The 10 X 38mm fuse can be used standalone with the DIN mount string fuse holder to fuse a single circuit or as a bank of fuses in a solar combiner box.
Availability: In Stock - Delivery 1-3 days or collect from near Lewes
One pole DIN rail mount fuse holder for 10 X 38 type fuses, suitable for protecting and isolating solar panel strings between the array and the charge controller input for example.
Rated to 1000VDC, 32A, accepts up to 16mm² cable. For use stand alone or for incorporation into a PV combiner Box with the 13 way bus bar and feeder terminal to take off the supply to a solar charge controller or solar inverter.
