What is anti-islanding protection?

Anti-islanding protection is a US-required safety feature that is built into all grid-tied and hybrid grid-tie inverters that operate in the US. It may not be built into some inverters meant to operate in different countries. Anti-islanding protection is a way for the inverter to sense when there is a problem with the power grid, […]

What is “Net Metering” and how does it work?

When using a grid-tied solar system, power from the solar kit is used as a supplement to the power grid that is feeding your house. During peak hours, when the most energy is being used, the load is usually more than the PV system can provide and the needed extra energy is taken from the […]

What is the difference between a PWM and MPPT charge controller?

Pulse-Width Modulating (PWM) charge controllers use complex algorithms to determine the amount of charge going to a battery and slowly taper off charging as the battery becomes full. One of the greatest advantages of PWM controllers is that they have been around for many years, are cheaper, and are available in a wider variety of […]

What effect will temperature have on the efficiency of my solar PV system?

Each component in the kit will have a different reaction to the temperature but the two that react most notably are the solar panel and the battery bank. Solar panels perform better at lower temperatures due to the inner workings of the panel. Solar panels are created by using two different types of silicon, called […]

What are Standard Test Conditions (STC)?

STC stands for “Standard Test Conditions” and are the industry standard for the conditions under which a solar panel are tested. By using a fixed set of conditions, all solar panels can be more accurately compared and rated against each other. There are three standard test conditions which are: 1. Temperature of the cell – […]

Why does my solar panel not seem to work even though only one small part of it is covered up/in the shade?

A solar panel is actually just a casing that holds multiple small solar cells. These are the blue or dark-blue squares inside the solar panel that are actually absorbing the light and producing the energy. Each individual cell has its own voltage and amperage that are normally both very small. By combining these small cells […]

What is a “dead” battery?

Because most of our solar kits for any application use rechargeable batteries that are charged externally using a solar panel, the question of what constitutes a “dead” battery often comes up. Batteries only store power, and over time their capacity to hold this energy naturally decreases. A battery is only branded as “dead” when it […]

What wire gauge should I use for my system?

Additional wire may be required based on the customer’s specific placement of components. Using the proper wire gauge ensures that not only will the system be able to transfer energy without significant voltage loss, but also that the wires will not fail during operation due to overheating or melting. It is important to note that […]

Can I use my own generator, in addition to using solar panels, to charge the batteries in my kit?

Although most of our inverters do support using a generator for power, we do not include generators with our kits. In most cases inverters with one input may have an external transfer switch connected which allow for both the solar panel array and the generator to be connected, and manually switched between. It is strongly […]

How long will it take to install a solar PV system?

20-30 years ago when solar technology was considered relatively new, installing a complete system used to be a very long and involved process that required a site inspection and many other preliminary steps . Today, a complete solar kit installation takes only a few weeks, from the planning and configuring stages through to the actual ordering […]

What are the differences between Solar PV system and solar thermal/hot water system?

Although both solar system capture the energy from the sun, but the ultimate purpose of the system is different. The Solar PV system is to produce electricity. And of couse the hot water system transit water to be hot for swimming pool, domestic, and residential use.

What is the difference between monocrystalline, polycrystalline, and thin film solar panels?

  Monocrystalline solar panels are panels cut from single slabs of silicon. They are identifiable by their consistent color throughout the panel and are often a dark blue to almost black color. Historically, monocrystalline panels have had the highest efficiency (around 15-17%) because being cut from a single slab of silicon allows a greater level […]
