PV Mounting Systems

Solar Panels can be integrated in a variety of ways. Panels can be mounted flush to existing angled roofs, most common for residences. For most commercial buildings with flat roofs a solar array requires a ballasted, non-penetrating mounting system. For areas where mounting to an existing structure is impractical, a ground mount can be constructed to secure and angle the panels. Grounds mounts are constructed from steel supports with concrete footings. The rest of the mounting structure is built from aluminum or galvanized steel. We offer ground mount systems in which we build a structure to install the solar PV panels as an aside to your property. E2sys is committed to offer customized solutions that will ensure optimal cost efficiency and the payback period you deserve.

Types of Solar Panels

Monocrystalline Silicon Panels:
Monocrystalline panels use crystalline silicon, a basic semiconductor material. The way to identify whether a panel is Mono or Poly is simple. A Mono panel has individual cells. A Poly type panel is solid with what looks like flakes of silicon pressed together. Monocrystalline panels are typically 15-18% efficient, meaning that for every unit of solar energy that hits the cell, the panel can convert 15-18% of this energy into electricity. These panels are usually more expensive.

Polycrystalline Silicon Panels:
Polycrystalline, or multicrystalline, photovoltaics use a series of cells in place of the single large cell used in monocrystalline panels. They are usually less efficient and therefore less expensive than Monocrystalline panels.

Amorphous Silicon or Thin Film Panels:
Thin-film panels are the lowest efficiency of any current photovoltaic technology at 5-6%. The primary advantage of thin-film panels lies in flexibility.

Inverters

Off Grid Inverter:
The purpose of an “Off Grid inverter” is to simply convert DC power from your batteries, wind generator or petroleum generator with no need to ever connect to the grid and sell power back.

Grid Tied Inverter:
This inverter is the most common for PV systems. It takes the power that your solar panels produce and puts it back into the Utility Company's lines. With the proper meter, this effectively allows you to net meter. A Grid-Tied Inverter constantly communicates with the Utility Grid, and will automatically shut off the system in the case of a Power Outage.
