Product description
60 cell multi-crystalline solar module. 40mm natural anodised frame. IP65 rated Jbox, 1m solar cable and a pair of MC4 connectors.TÜV SÜD,SABS ISO 9001:2008 certified.
Nominal voltage refers to the voltage of the battery that the module is best suited to charge; this is a leftover term from the days when solar modules were only used to charge batteries. The actual voltage output of the module changes as lighting, temperature and load conditions change, so there is never one specific voltage at which the module operates. Nominal voltage allows users, at a glance, to make sure the module is compatible with a given system.
Open circuit voltage or VOC is the maximum voltage that the module can produce when not connected to an electrical circuit or system. VOC can be measured with a meter directly on an illuminated module's terminals or on its disconnected cable.
The largest challenge of photovoltaic technology is the efficiencies of such solar systems. While utilizing such systems draws a great interest due to the long term returns of profit, the efficacy needs to come a long way before making it plausible to be introduced in all consumers of electricity.

solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating.
A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricityin commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, a solar inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

- Q: what do I need to do to disconnect a solar panel from a battery to protect the panel?
- Know that solar panels almost always incorporate a blocking diode to prevent a battery from back-feeding through an un-illuminated panel. Know that solar panels are usually connected to a battery via an electronic switching charge controller, not directly connected. Know that when a solar panel is open-circuited (disconnected from everything) it's terminal voltage will rise to almost twice it's nominal voltage. (22V is common for a 2V panel), unless it is stored in total darkness.
- Q: What is the warranty period for solar panels?
- The warranty period for solar panels typically ranges from 10 to 25 years, depending on the manufacturer and the type of panel.
- Q: I'm re-doing my roof. Is it workable?Can I get a government grant or something to put solar panels on my roof?I know they did something like that for windows.
- I take it you are in the uk,no grants available that I know of .Affordability is down to how wealthy you are,cost effectiveness? you may!!!recover the cost over about 20 to 30 years depending on your power use,against what you would pay a power Co. Worth while? frankly just another scheme to prise money out of the public,in the name of ecology or cost saving.
- Q: How do solar panels affect the property's green certification?
- Solar panels can positively impact a property's green certification by enhancing its sustainability and energy efficiency. The installation of solar panels reduces reliance on non-renewable energy sources, decreases carbon emissions, and promotes the use of clean energy. This aligns with the requirements of most green certification programs, which prioritize environmental responsibility and conservation. Therefore, incorporating solar panels can contribute significantly to a property's green certification and help demonstrate its commitment to sustainable practices.
- Q: How do solar panels affect the property's operating costs?
- Solar panels can significantly reduce a property's operating costs by generating clean and renewable energy, thereby reducing or even eliminating the need for traditional electricity from the grid. This results in lower monthly utility bills, as well as potential incentives such as net metering or feed-in tariffs that allow excess energy to be sold back to the grid. Additionally, solar panels require minimal maintenance and have a long lifespan, further contributing to cost savings over time.
- Q: How do solar panels affect the overall comfort of a building?
- Solar panels can positively impact the overall comfort of a building by reducing energy costs and improving indoor temperature control. They generate clean and renewable electricity, which can power various systems such as heating, ventilation, and air conditioning (HVAC) units. This helps to regulate the indoor temperature more efficiently, leading to a more comfortable environment for occupants. Moreover, solar panels can also reduce reliance on the grid, ensuring a more reliable energy supply and enhancing the comfort and stability of the building.
- Q: I want to know how to hook up a Solartech SPM020P-R, 20W Solar Panel to a single outlet that you can but at a store.
- That solar panel puts out about amp (in round numbers). If you are talking about a 20vac outlet, you'll have to send the output of the solar panel through an inverter. That brings it up to 20vac. 20 watts at 20 volts means you'll only be able to draw 0.6667 amps. With an inverter at 85% efficiency, you'll only get about 0.4 amps. That would barely light a CFL. 20 watts of power at 7 volts = amp (in round numbers) 20 watts of power at 20vac = 0.6667 amp (in round numbers) Power (watts) = current x voltage. If you increase voltate, you must decrease current to get the same watts. Watts is the common denominator in power measurement.
- Q: How to Compare Solar Panels? ?
- Every okorder for links and faq's.
- Q: Can solar panels be used in areas with high humidity or saltwater exposure?
- Yes, solar panels can be used in areas with high humidity or saltwater exposure. However, the performance and longevity of the panels may be affected by these environmental factors. It is important to choose solar panels specifically designed for such conditions and regularly maintain and clean them to ensure optimal efficiency.
- Q: I wanna get a solar panel to charge or 2 car batteries. Then connect the battery to a 800watt power inverter so that I can power a tv. Will the 8watt solar panel charge my batteries and around in how long?I just wanna use the panel to charge the batteries, no to use the panel directly with my electronics. Thanks for your answer and help me with that.
- How about wind power? Check out this site, you can build one for under two hundred and get free batteries.
