FAQs about solar energy & products
What are photovoltaics (solar electricity) ?
Photovoltaic (PV) devices generate electricity directly from sunlight through an electronic process that occurs naturally in certain types of material, called semiconductors. Electrons in these materials are freed by solar energy and can be induced to travel through an electrical circuit, powering various electrical devices or sending electricity to the grid.
How does solar power work?
PV panels capture the sun’s energy, channel it through discreetly placed wires to an inverter, where it’s converted to electricity to power your home. When your solar power system produces more power than you need, it feeds the power back into the electricity grid.
What is an MPPT solar Charge Controller?
The MPPT charge controller ensures that the loads receive maximum current to be used (by quickly charging the battery).
Maximum power point could be understood as an ideal voltage at which the maximum power is delivered to the loads, with minimum losses.
This is also commonly referred to as peak power voltage.
What is the maximum power point (MPP)?
The maximum power point (MPP) describes the point on a current voltage (I-V) curve at which the solar PV device generates the largest output i.e. where the product of current intensity (I) and voltage (V) is maximum.
The MPP may change due to external factors such as temperature, light conditions and workmanship of the device.
In order to ensure maximum power output (Pmax) of a solar PV device in view of these external factors, maximum power output trackers (MPPT) may be operated to regulate the resistance of the device.
How do MPPT charge controllers work?
Anyone familiar with the charging and discharging characteristics of the battery is familiar to the fact that the voltage of the battery varies with its charge content.
As current flows from a high potential to low potential, the steeper the gradient or voltage difference, the greater is the flow of current.
This potential gradient could be made steeper by two ways:
By increasing the output voltage of the Solar Panel
By decreasing the voltage of the battery (discharging the battery)
