What is photovoltaic (solar electricity) or “PV”?
Photovoltaics, or PV, refers to technology that converts light into electricity. The term comes from “photo,” meaning light, and “volt,” referring to electrical power. PV materials generate electricity when exposed to light, using the same scientific principles discovered in the 18th century. This is the foundation of how JEH Solar LLC designs solar energy systems for homes and businesses.
How can we get electricity from the sun?
Certain semiconductor materials release electrons when exposed to sunlight — a process known as the photoelectric effect. When photons strike a PV cell, their energy transfers to electrons, allowing them to move and create an electrical current. This is the fundamental process behind how solar panels generate electricity for your home.
What are the components of a photovoltaic (PV) system?
A PV system includes solar panels, batteries (for storage systems), a charge controller for stand-alone setups, an inverter for converting DC to AC power, wiring, and mounting structures. JEH Solar LLC customizes these components based on your home’s needs and energy goals.
How long do photovoltaic (PV) systems last?
A well-designed and properly installed PV system can last more than 20 years. Solar panels themselves often last 30+ years because they have no moving parts. The key to longevity is a professional installation — something JEH Solar LLC specializes in.
Can I use photovoltaics (PV) to power my home?
Yes. PV systems can power lights, appliances, heating and cooling equipment, and more. Panels are typically mounted on a south-facing roof or wall and can be integrated into homes of all styles.
Can I use photovoltaics (PV) to power my business?
Solar works extremely well for commercial buildings. PV can power lighting, equipment, signage, parking lot structures, and more, offering long-term cost savings and clean energy.
How do I know if I have enough sunlight for PV?
Solar systems require consistent access to sunlight, ideally without shading. PV works in nearly every climate and even performs better in cooler weather. JEH Solar LLC evaluates your roof orientation and shading to ensure optimal system performance.
How big a solar energy system do I need?
It depends on your energy usage, roof size, budget, and whether you want to offset all or just part of your electricity bill. JEH Solar LLC calculates system size based on your exact energy profile.
Why should I purchase a PV system?
Homeowners choose solar to reduce utility costs, increase property value, and cut reliance on fossil fuels. A properly designed system can also provide backup power during outages and protect you from rising electricity rates.
