Solar Energy Knowledge Base

Solar (photovoltaic) Panels

See all solar panels

Solar panels are all made of silicon cells. They are either monocrystalline or polycrystalline. We have grouped solar panels into two categories: low voltage (12V and 24V) and large format.

The solar cells in a low voltage panel are configured in a way that the output will be nominal 12 or 24 Volts DC. They are used in simple battery charging applications to keep the voltage constant across the system. These panels are available in sizes ranging from 5W to 190W. See 12V and 24V solar panels.

Large format panels are made with 60, 72, or 96 solar cells. The output voltage of these panels varies but tends to be higher than 40 Volts DC. These panels are preferred in multiple applications, from residential and commercial systems to large power plants. See our solar panel selection guide.

Solar Power Electronics
Inverters and Charge Controllers

See grid-tie inverters | See MPPT charge controllers

The power from the solar panels is not stable, and for practical purposes, it can’t be used as-is. An electronic device is required to harness solar power and convert it into useful energy. Systems that are interconnected to the grid use an inverter that converts the DC power from the panels into AC power compatible with the electric grid. When the solar power is used to charge batteries, a charge controller is needed between the panels and the batteries to protect the batteries from overcharging.

Off-Grid Inverters

See off-grid inverters

Off-grid systems can be fully configured in DC current, therefore not needing an inverter. The inverters used in off-grid systems convert the DC energy stored in the batteries into AC power to operate standard appliances. The output of a DC/AC inverter is equivalent to power in a home outlet (120VAC) or the power coming from the utility grid (240VAC).

Batteries and Energy Storage

See deep cycle batteries

The batteries used in renewable energy systems are known as deep cycle batteries. Even with new technologies, lead-acid batteries are widely used in renewable energy systems. Deep cycle batteries come in two presentations: flooded and valve-regulated (VRLA). VRLA batteries are also known as maintenance-free; the two most common types of VRLA batteries are gel and glass-mat (AGM).

Battery banks can be configured at any desired voltage. However, it is rare to see a bank with a nominal voltage other than 12V, 24V, or 48V. As a rule of thumb, portable and mobile systems are 12V. Recent RVs, boats, and custom vans are wired at 24V. 48V is the default voltage for medium and large power applications.

Wind and Other Power Sources

See wind energy products

Solar is the most common renewable energy source; however, in specific locations, it makes sense to add other sources such as wind and hydropower. Wind power has the advantage that it is not limited to daily cycles, and it tends to be available when the sun is not. For example, wind can be harnessed at night or on stormy days, making it an ideal complement to solar for stand-alone systems in remote locations.

Balance of Systems (BOS)

See BOS components

As you can imagine, there are other components needed to operate a renewable energy system safely. For circuit protection, think of breakers, fuses, cables, connectors, surge protectors, boxes, and electrical enclosures. For the installation, you might require a racking system to mount the solar panels or a combiner box for the PV circuits.
