The idea behind solar power is simple. Every day, whether cloudy or clear, photons of light hit your roof’s solar panels, which converts those particles of light into electrons of direct current (DC) electricity. The electrons flow out of the solar panel and into an inverter and other electrical safety devices. The inverter converts the DC electricity into alternating current (AC), the kind of power your television, lights, computer, toaster, and other household devices use when plugged into the wall outlet.

A net energy meter keeps track of the all the power your solar system produces, and any energy that you do not use immediately goes back into the electrical grid through the meter. At night or on cloudy days, when your system is not producing more than your building needs, you will consume electricity from the grid as normal. Your utility will bill you for the net consumption for that billing period and provide you with a dollar credit for any excess during that billing cycle. You can carry your bill credit forward for up to a year.


Peak Solar provides all the components you will need to install your solar power system, which is designed for long life and sustainable savings.

Solar cells are small, square-shaped panel semiconductors made of silicon and other conductive materials, manufactured in thin film layers. When sunlight strikes a solar cell, chemical reactions release electrons, generating electric current. Solar cells are also called photovoltaic cells or PV cells and can be found on many small appliances such as calculators.

PV systems typically are made of the following components:

  • PV modules (groups of PV cells), commonly called PV panels
  • One or more batteries
  • Charge regulator or controller for a stand-alone (off-grid) system
  • Inverter to covert solar power from DC to AC
  • Wiring
  • Mounting hardware or framework

A PV module arranges individual PV cells, and the modules are grouped together in an array. Some arrays are set on special tracking devices to follow sunlight all day long and improve system efficiency.

For maximum effectiveness, a PV system needs unobstructed access to the sun’s rays for most or all of the day. Shading can significantly reduce energy output, although climate is not a major concern. PV systems are relatively unaffected by air temperatures, and snow cover on solar arrays typically melts quickly because panels are exposed directly to the sunlight. Abundant year-round sunshine makes solar energy systems useful and effective nearly everywhere in states like California and Arizona, for example.

The size of your solar system depends on several factors:

  • Your average energy usage
  • The size of your roof or grounds
  • Your budget
  • How much energy you want to generate

Peak Solar can help you determine your energy needs and the best solar system for those needs.


PV systems today can be blended easily into both traditional and nontraditional homes, powering appliances and electric systems. PV cells can be installed as stand-alone modules attached to your roof, on separate systems, or using integrated roofing materials with dual functions: roofing shingles with built-in solar cells.

The most common practice is to mount modules onto a south-facing roof or wall. PV systems likewise can be blended into most commercial buildings. You will find PV systems used outdoors for security lighting as well as in structures that serve as covers for parking lots and bus shelters.

You could install a PV or solar electric system yourself. But to avoid complications, you may want to hire a professional contractor experienced in installing solar systems. Peak Solar can provide you with complete technical support or connect you with an experienced contractor.

While they are sophisticated electrical systems, PV systems require little maintenance. The basic PV module (an interconnected, enclosed panel of PV cells) has no moving parts and can last more than 30 years. The components are designed to meet strict dependability and durability standards to withstand the elements.

The best way to ensure and extend the life and effectiveness of your PV system is to install and maintain it properly. Most PV system problems occur because of sloppy system installation. Many states offer rebates and incentives for installing solar systems, but only if they meet certain requirements, such as a 10-year system warranty.

Solar energy is always evolving and becoming more efficient and affordable. Peak Solar sells only monocrystalline and polycrystalline solar panels, the familiar black and blue panels you see almost everywhere today. But other solar technologies point to a brighter future for solar power.

Concentrating solar power (CSP) systems concentrate the sun’s energy using reflective devices such as troughs or mirror panels to produce heat that is then used to generate electricity.

Solar water heating systems contain a solar collector that faces the sun and either heats water directly or heats a working fluid that heats water.

Transpired solar collectors, or solar walls, use solar energy to preheat ventilation air for a building.
