LG’s NeON™2 solar panel is one of the most efficient commonly available 60-cell modules on the market. LG considers the fact that the amount of energy generated by solar panels differs from day to day due to factors such as weather, temperature, and shading. This is why they create their solar panels with quality and efficiency in mind.

As the global specialist in energy management, Schneider Electric provides complete photovoltaic solutions for any size installation, from grid‐tie residential rooftops and utility‐scale farms to off‐grid solar and battery backup application.

Exeltech inverters have an MTBF (mean time between failure) in excess of 20 years and offer the most competitively priced ultra-reliable true sine inverters available anywhere. Exeltech provides back up power for the communications room in every U.S. Embassy, worldwide.

The latest and greatest Fronius grid-tie inverters are the IG Galvo and Primo lines, which are fully NEC 2014 and UL compliant. They come with built-in ground fault protection, DC reverse polarity protection, islanding protection, over temperature protection, and arc-fault circuit protection.

The Sunny Boy solar inverters characterize the technology and quality-leadership of the company. They are optimally suitable for use in small and mid-range systems. They impress with first class efficiency, user-friendliness, and reliability.

The Enphase Energy Solar Micro-inverter system is a set of small units that connect directly to each solar module to convert DC power into grid-compliant AC power and transmits valuable performance data on each module to the system owner.

A Conext XW solar system provides up to 36 kW by using modular components. All components communicate with each other with out‐of‐the‐box network capability. They include the Conext XW Inverter/Chargers, the Solar Charge Controllers, the Conext XW Automatic Generator Start (AGS), and the Conext XW System Control Panel (SCP).

Whether you lack the experience or knowledge to build your own system or if you simply want to save time on installation, the MidNite Solar Prewired E-panels are an excellent option.

Grid-Interactive? What does THAT mean?? Grid-interactive is kind of a hybrid system, battery-based but they also feed any excess power back to the grid and draw from the power grid when the solar panels are not producing enough.

This table lists the American Wire Gauge (AWG) sizes for copper conductors. In addition to wire size, the table provides values for load (current) carrying capacity, resistance, and maximum frequency. The resistance and skin depth noted are for copper conductors only.

Includes 12, 24, and 120-volt charts and a metric to AWG size conversion table. This is a five percent table which means at these amperage ratings at the listed distances, 5% of the power would be lost to resistance.

MC connectors are specially designed for low contact resistance and good stable connections under a wide range of conditions. MC means "multi-contact." The term "multi-contact" comes from the fact that the connectors have a bunch of little spring loaded gold plated fingers that ensure good contact.

Numerous charts and lists have been published with long lists of appliances and how much power they draw. You are then supposed to add up all the watts, then find out how many hours of sun you get, etc etc.

An "RV system" (small boat and cabin systems are practically identical) can mean different things to different people. It might be just a small 5-watt panel that keeps the battery charged up between a few trips a year or over the winter.

An MPPT, or maximum power point tracker is an electronic DC to DC converter that optimizes the match between the solar array (PV panels), and the battery bank or utility grid. To put it simply, they convert a higher voltage DC output from solar panels (and a few wind generators) down to the lower voltage needed to charge batteries.

A charge controller or charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery. Most "12 volt" panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging.

Lithium batteries stand apart from other battery chemistries due to their high energy density and low cost per cycle. However, "lithium battery" is an ambiguous term. There are about six common chemistries of lithium batteries, all with their own unique advantages and disadvantages.

Absorbed Glass Mat batteries are constructed differently than the traditional flooded battery. This write-up covers mainly the Concorde Sun-Xtender AGM's, but also applies to most other brands of deep cycle AGM batteries.

There is more to comparing batteries than just cost or amp-hour ratings. For example, based only on cost, the Concorde AGM's do not look so good. On the other hand, you probably would not want to store a flooded battery in your computer room. There is no one best battery for all applications.

When designing an off-grid (not connected to utility power) solar or wind power system, it's very important to have an accurate estimate for how much energy you need.

Lightning is the number one cause of catastrophic failures in solar electric systems and components. The first major reason is that many PV systems are poorly grounded and poorly protected. That is also the 2nd and 3rd major reason.

This information is mainly aimed at reducing or eliminating radio, TV, cell phone, and other electronic noise and interference in photovoltaic and other DC powered systems and from equipment used in PV systems.

An "array" may be one panel or many in series and may range from a single panel 12-volt up to multi-panel high voltage arrays for grid-tie systems.

The following is a listing of terms used primarily in the PV industry, but some general and solar heating terms are also included.

You often see inverters rated in volt-amps (VA or va) instead of watts. For a perfect resistance, such as a heating element, watts and VA are essentially the same. However, many appliances, especially motors, are not a "perfect" load. Thus, the watts actually used may be less than the VA - but the inverter sees the VA. The motor or appliance may be using only 100 watts, but the inverter sees an "apparent" power of 150 VA.

An off-grid solar electric system involves working with both alternating current (AC) and direct current (DC) voltages. These voltages can be lethal if all safety precautions are not followed.
