Description
Nasa Solar Panels

Nasa Solar Panels - At just 3.5mm thick, these 12 volt, semi flexible solar panels are robustly constructed on a fibre glass substrate and are protected by a scratch proof transparent Tedlar polymer which is tough enough to withstand being stepped on when wearing soft soled shoes.
The efficient & stable polycrystalline cells are encapsulated between two tough outer layers so the whole panel is weatherproof.
The panels can be gently flexed (in one dimension) to follow a smooth curve, such as a coach roof, by up to 2.5cm per 100cm of panel length.
• Four, grommet finished, holes for screw fixing.
• Panels can be glued into position using mastic
• Fitted with sealed junction box with 2.5m output cable, connector & fuse protected crocodile clips
• Internal blocking diode prevents reverse current drain at night
• Inline 3 Amp fuse included

Available in 2 sizes/outputs:

Code: 120073 - 10Watt
• Size: 265 x 360mm

Code: 120074 - 20Watt
• Size: 350 x 495mm

Electrical connection is simple, though the use of a solar regulator is recommended to prevent overcharge if the system is to be left unattended for long periods or the solar panel to battery ratio exceeds the minimum of 10W to 100Ah.

Questions & Answers
Questions & Answers
Can you tell me what the minimum size battery should be to power this PV panel so it keeps fully chgarged under normal daylight conditons? David Hart

Solar Panels use many photovoltaic cells to convert the suns energy to electrical power and do not need a power source of their own to operate. A 12V battery needs a charging voltage above 13.6V to be applied in order to charge. All solar panels designed for 12V batteries will output this voltage (when in full sunlight) irrespective of size. The size of the panel determines the charging current - the higher the current the faster the battery will charge. So a 10Watt panel will charge at around 0.7A and a 20W panel will charge at around 1.4A. Panels bigger than 10W will require a solar charge regulator as direct connection of larger can cause battery gassing which leads to internal battery plate damage. https://www.force4.co.uk/item/Solar-Technology/Dual-Battery-Solar-Charge-Controller/WJD For your application - In order to ascertain the current required (and therefore panel size) to keep your battery fully charged you will need to calculate the maximum current drawn from the battery from all the devices connected to the battery. The easiest way is to measure using ammeter .The charge current from the solar panel must greater than the current drawn in order to charge the battery. Also the battery charge state has to be accounted for as the charge time will be a lot longer to charge a battery with a low charge. I hope this helps, please combe back if you need any further assistance.
