Clean New Energy – Photovoltaic Solar Energy

Clean new energy, particularly solar, combines science, nature and tech to steer us toward sustainability. It aims to help reduce air pollutants, greenhouse gases and dependence on fossil fuels.

Solar energy harnesses sunlight’s power and has emerged as a leading renewable energy source. Its technology uses photovoltaic cells that convert solar irradiance into electricity through the photoelectric effect by exciting electrons to produce electric current.

Solar Panels

Solar PV panels convert the sun’s light energy into electricity. These are the panels you see on rooftops and in fields upstate, and they create all of the clean electricity that powers homes, businesses, and NYC government facilities. Producing your own solar energy reduces your reliance on the local power grid and cuts utility bills. It also helps to reduce greenhouse gas emissions, which contribute to climate change and air pollution, a major threat to human health.

Solar cells are made of semiconductor materials, like silicon, that absorb the sun’s rays and turn them into electricity. When these cells are connected together, they create an electrical circuit that generates electricity. A single panel (module) generates enough energy for a home or small business, but multiple panels are used in a larger system, called an array. The array is wired to an inverter that turns the DC electricity from the solar panels into alternating current, the type of electrical power that flows through appliances and lights.

Solar panels require very little maintenance and are low-cost, making them a cost-effective solution to help combat global warming and address air quality problems in New York City and elsewhere. Because they don’t emit pollutants into the atmosphere, they can help prevent environmental degradation, such as acidifying land and water ecosystems or corroding buildings and vehicles. They also help eliminate the need for fossil fuels, which are a major source of greenhouse gases that contribute to global warming and air pollution.

Solar Batteries

A solar battery allows you to store the clean electricity your panels generate when the sun isn’t shining. This energy can then Clean new energy photovoltaic solar energy be used at night or on cloudy days, providing you with a more sustainable way to power your home and avoid paying the electric utility bill.

Solar batteries can be configured in a variety of ways to meet your specific needs. You can choose a critical backup mode, a self-consumption mode, or a combination of both. Battery sizing is also an important consideration, and depends on your household’s average daily energy consumption and on the appliances you want to run on your solar system.

When selecting a solar battery, you should consider its cost and performance, as well as its environmental impact. Using a lead-acid battery with a flooded design, for example, can release toxic chemicals into the environment during charging and discharging cycles. Other types of batteries, such as lithium-ion, are gaining popularity for their ability to offer longer lifespans and greater efficiency.

Solar Water Heating

Home water heaters use a lot of energy. A solar water heating system takes advantage of free sunshine to heat stored water without the need for fossil fuels. A home solar water heating system reduces energy consumption, which is good for the environment and your wallet.

A solar water heating system uses collectors that are mounted on your roof, a tank to store the heated water and a controller. Solar hot water systems are available in a variety of configurations to meet specific energy requirements and latitudes. There are two main types of solar hot water systems: direct circulation and indirect. Direct systems use a pump to circulate household water through the collectors. These are best suited to climates where freezing temperatures rarely occur. Indirect systems use a heat-transfer fluid (usually a mixture of water and antifreeze) that carries the sun’s thermal energy into the storage tank. These are more suitable to cold climates, as the heat-transfer fluid is designed to be freeze-resistant.

The front and back surfaces of the solar photovoltaic cell in a solar water heating system are coated with a special semiconductor material, which has an imbalance of electrical charges like the negative and positive terminals of a battery. As sunlight passes through the cell, electrons are drawn to the surface where they are trapped by the semiconductor. These electrons flow through the conductors in an electrical circuit to generate electricity.

Solar Ventilation

Solar ventilation systems use solar power to generate energy to operate roof-mounted vents in homes and other buildings. The vents help to circulate air from the attic and prevent excessive heat buildup that can affect the overall temperature of a building. Solar powered ventilation systems consist of a solar panel, a fan and ductwork. The solar panel is installed on the roof and positioned to receive maximum sunlight. The fan is located in the attic and connects to a duct that helps to circulate the air. When the air in the attic reaches a set temperature, the solar-powered fan is activated, drawing hot air out of the attic and venting it to the outside.

Solar Ventilation Preheat

A solar-powered roof ventilation system consists of a collector mounted on a south-facing wall and a duct connecting it to the building’s ventilation system. The collector consists of a dark-colored aluminum or corrugated metal wall with numerous perforations.

When a thermostat calls for heat, the solar ventilator preheat opens and simultaneously closes the exterior air damper. The duct leads to the building’s plenum, which contains a solar air heating unit that uses the sun’s radiation to warm the ventilation duct. The duct is sealed with perimeter flashing that has insect mesh and weep holes to allow for drainage.

These systems are a simple and cost-effective way to reduce your reliance on fossil fuels and save money on energy bills. They also provide a number of additional benefits, including extending the life of your roof, decreasing moisture buildup and helping to avoid damaging ice dams in winter.
