Half Cut Solar Panel
A half-cut solar panel is a module composed of solar cells, which are cut in half (or sliced in two) to reduce resistive losses and increase module efficiency. By cutting the cells into smaller pieces, the current density is decreased, which reduces power loss due to resistance and enables the cells to produce more power. The use of half-cut solar panels can reduce the effect of shading and may even improve energy harvesing in low-light conditions.
What is PERC in solar panel?
Over the last few years PERC solar panels have become increasingly popular. PERC, which stands for Passivated Emitter and Rear Cell or Passivated Emitter and Rear Contact, is a new technology aimed to achieve higher energy conversion efficiency by adding a dielectric passivation layer on the rear of the cell.
What is Monocrystalline solar panel?
Monocrystalline solar panels (or mono panels) are made from monocrystalline solar cells. Each cell is a slice of a single crystal of silicon that is grown expressly for the purpose of creating solar panels. In the lab, the crystal is grown into a cylindrical log shape called an ingot and is then sliced into thin discs.
Best Applications for Monocrystalline Solar Panels
- Smaller applications
- Areas with less sunlight
- Efficiency, not cost, is more important
- Appearance is an issue
Monocrystalline solar panels are best for areas where space is limited since they produce more electricity on a smaller scale than poly panels. Monocrystalline solar panels can draw out the maximum amount of energy even in areas of lower sunlight. So, they are ideal when the goal is efficiency more than cost. Though all solar panels are bulky, monocrystalline solar panels, with their dark hue, fade into the background better than poly units. Monocrystalline solar panels tend to have better heat tolerance than polycrystalline panels. So, they are a good choice for areas of extreme heat, such as desert environments.
What is Monocrystalline photovoltaic solar power panel?
Monocrystalline PV panels are made from a single piece of silicon, therefore making it easier for electricity to flow through. They have a pyramid cell pattern which offers a larger surface area enabling monocrystalline PV panels to collect a greater amount of energy from the sun's rays.
What is a Tier 1 solar panel?
It's quite apparent that the term "Tier 1" gets used quite liberally and frequently by many solar sales companies who use it to describe their solar panels as being of a high quality.

How Do Solar Panels Work?
Solar panels collect clean renewable energy in the form of sunlight and convert that light into electricity which can then be used to provide power for electrical loads. Solar panels are comprised of several individual solar cells which are themselves composed of layers of silicon, phosphorous (which provides the negative charge), and boron (which provides the positive charge). Solar panels absorb the photons and in doing so initiate an electric current. The resulting energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their atomic orbits and released into the electric field generated by the solar cells which then pull these free electrons into a directional current. This entire process is known as the Photovoltaic Effect. An average home has more than enough roof area for the necessary number of solar panels to produce enough solar electricrity to supply all of its power needs excess electricity generated goes onto the main power grid, paying off in electricity use at night.
In a well-balanced grid-connected configuration, a solar array generates power during the day that is then used in the home at night. Net metering programs allow solar generator owners to get paid if their system produces more power than what is needed in the home. In off-grid solar applications, a battery bank, charge controller, and in most cases, an inverter are necessary components. The solar array sends direct current (DC) electricity through the charge controller to the battery bank. The power is then drawn from the battery bank to the inverter, which converts the DC current into alternating current (AC) that can be used for non-DC appliances. Assisted by an inverter, solar panel arrays can be sized to meet the most demanding electrical load requirements. The AC current can be used to power loads in homes or commercial buildings, recreational vehicles and boats, remote cabins, cottages, or homes, remote traffic controls, telecommunications equipment, oil and gas flow monitoring, RTU, SCADA, and much more.
Solar thermal power plant
A solar thermal plant is a facility designed for converting solar energy into electricity through a conventional thermodynamic cycle. However, unlike thermal power plants that work by using fossil fuels, solar thermal power plants use a completely eco-friendly energy source like sunlight. The technology used to produce electricity is slightly different depending on the type of solar thermal plant we're talking about, but its operating system is similar.
A solar thermal power plant concentrates the solar radiation to heat a fluid with thermally conductive properties and raise its temperature until it's converted into steam. It's then fed to a turbine. Here, the thermal energy is converted into mechanical energy, which is transmitted to an alternator where its final transformation into electricity takes place. Once the thermodynamic cycle has been completed, the steam is returned to a condenser where it recovers its liquid state and the process is repeated again.
From an efficiency point of view, it's important to take into account that the performance of a solar thermal plant depends on the hours of sunshine and weather conditions. Therefore, these power plants also have a storage tank that allows the energy obtained to be stored to use it when necessary.
