Solar Photovoltaic (PV) Panels
Solar Photovoltaic (PV) panels convert the sun’s energy to electricity utilizing no moving parts. They have been around for more than a half century and many of the early panels are still producing power. Most PV panels on the market today have a 20-25 year warranty and an expected life of 50 years.
There are many different types of solar photovoltaic PV panels available on the market. Some are built for lowest production cost, others are built for longest life, while still others are built to have the highest production density per square foot. There is an entire line of transparent PV panels that are designed to be aesthetically pleasing from the front or back. There are even PV panels that replace your roof shingles.
There are benefits and drawbacks to each, and depending on the unique scenario of your application one may be a better choice than the other. Let us help you get the right panel for the right price.
At Pennsylvania Renewables we monitor all of the rebates and incentives that may apply to your solution. In many cases, these incentives can drive the pay-back period for the entire system to less than 5 years. If you hate paperwork and filling out forms, we can do it for you. We want all of our customers to take advantage of these incentives. See Our Installations
Thermal Solar panel designs
Thermal Solar panel designs include: hot-water production and hot-air production.
- hot-water production panels can supplement or replace a water-based heating system that currently uses gas or electric to heat the water.
- insulated tanks can be used to store hot water from solar panels to be used at night.
Currently there is no efficient way to store hot air for later use. Therefore, hot-air systems can compliment but not replace a forced air heating system
Both water and air production systems can be complicated to design and install, but we have the experience and knowledge to design and install either of these systems to fit your exact needs. We also design and build hybrid systems that can meet any special needs you may have at your home or business facility.
Wind turbines – Oldest Form of Renewable Energy Power Production
Wind turbines are one of the oldest and most well-known forms of renewable energy power production. There are two types of turbines: pumping turbines and electric turbines.
- pumping turbines turn spinning motion into up and down motion to operate water pumps at the base of the tower.
- electric production turbines have a generator attached to the drive-shaft of the blades that turns spinning motion into AC or DC current.
The energy produced can be used to charge batteries, or fed back onto the grid. When fed back to the grid, your electric meter spins backwards if your demand is lower than the electricity produced by your turbine. As a result, the electric company gives you a rebate for the unused electricity.
Turbines require special placement and do not work everywhere, but we can help determine if your location is suitable for a wind turbine.
Geo-Thermal Systems – Heat & Cool Your Home
Geo-thermal systems are the most efficient way to heat and cool your home. They typically save you more than 50% of your current power bill, no matter how efficient your current HVAC system may be. While most HVAC systems such as gas, propane, electric, or oil claim to be nearly 100% efficient, Geo-thermal systems are more than 400% efficient! How can that be? Simply because they don’t need to create heat, they simply “pump” heat from one place to another. Transferring the heat to or from your home takes only 25% of the energy as it does to create the same amount of heat using oil, gas, or electric.
Geo-Thermal heat pumps transfer heat from the ground below the frost line. This heat source provides a stable 55 degree temperature even when the air above is below zero. While regular heat pumps can be 400% efficient if the outside air is 55 degrees, when the air temperature drops below 55 degrees, the efficiency of the heat pump drops proportionately. When outside air drops to the the freezing point, the heat pump loses its ability to pull heat out of the air and a back-up heat source is required.
Geo-Thermal systems don’t lose their efficiency regardless of the air temperature. Because the ground temperature a few feet below the surface remains a constant 55 degrees, a geothermal heat pump continues to produce warm air at its peak efficiency. That is a comforting thought when it is freezing cold outside and you don’t need to lower the thermostat to be sure your next oil, gas, or electric bill won’t bankrupt your estate.
In addition to heating air, geothermal systems can also heat your regular hot water as well as hot water for hydroponic (in floor) heating. And, come Summer, your geothermal system will provide phenomenally efficient air conditioning because, no matter how high the air temperature, the ground below the surface remains at a stable 55 degrees.
Although they require a higher initial investment than other types of HVAC systems, the combination of utility savings and unique incentives available for geothermal provides a shorter payback period. And because our geothermal systems have a lower cost of ownership and longer life than most other types of HVAC systems, your ROI (Return on Investment) is certain to meet or beat your expectations. Let us show you how and why.
Battery Back-up Systems – Power When You Need It
Battery Back-up systems are incredibly convenient and provide an added level of comfort and safety for the homeowner. They are like an “instant-on” generator that continues to power your home if the main power goes out.
Most Solar PV systems are “grid tied”, meaning that when there is a power outage, the system is required to shut down. This is because the system can’t distinguish between a power outage and the utility company shutting the power down to do maintenance. A grid-tied-battery-backup system also disconnects from the grid during a power outage, however, a second output from the system powers your emergency circuits such as a well pump, sump pump, refrigerator, freezer, garage door opener, security system, necessary lighting and charging stations for your laptop and smartphones.
If the power outage occurs during the day, the system directly converts the sun’s energy to the AC power used in your home. At night, the system takes energy from a battery bank. If you never want to worry about a power outage again, ask us to include back-up with your PV system.
LED Lighting – Saves You Money
Regular light bulbs waste 95% of the energy they use to make heat and only about 5% to make light. However, the new and smartly improved LED Lighting is 90% efficient.
If light bulbs were cars, a incandescent light bulb car having a 30 MPG rating would have a rating of 60 MPG as a CFL (compact fluorescent) light bulb and an incredible 180 MPG rating as an LED! Although you can’t get a 180 MPG car, Pennsylvania Renewables can provide you the light-equivalent of that – LED light bulbs.
Lighting your home or business typically consumes 25-30% of your total energy usage. Switching to LED’s can shave 20-25% off your current energy bill.
Unlike LED’s a few years ago, the current design emits natural color: a soft white light that is also dimmable.
And forget about changing light bulbs every couple of months. LED bulbs last up to 50,000 hours. When combined with home automation systems that automatically set scenes, dim, or turn on/off your lights you can shave even more from your current energy bill.
At Pennsylvania Renewables, our goal is to add to your home’s value, comfort, and safety, while significantly reducing your power bills
Passive Solar Power Design – Using the Sun’s Position Year Round
Planning to build a new home? Do you want to lower the energy usage of your new-built home without spending a bundle? All you need to do is orient your home in the right direction and have more windows on the south side, and fewer windows on the north side.
The sun provides nearly 1000 watts of free energy for each square yard of surface area it shines on during the day. Blocking that energy out of your home in the winter is a waste of what nature gives you for free. Imagine how warm you would be if your 12 x 12 ft bedroom had sixteen 1000-watt hair driers running simultaneously! That’s how much energy the sun is able to send your way at no cost to you. All you need to do is provide windows to let the sunshine in.
Passive Solar Design simply takes into account the sun’s position year round. Let the sun in during the winter and keep it out during the summer. That is the first design principle of passive solar. It is not a new principle. The pioneers knew this when they built their log cabins, yet it seems to have been forgotten by new home designers.
The second principle of passive solar design is a bit more complicated. Once the sun is let in, find ways to store that heat for use at night or on cloudy days.
Let Pennsylvania Renewables show your architect or builder how to make your new home “sunshine friendly” We are not sun worshippers; it only looks that way. Not only will you be more comfortable in your new home, you will also save significantly on your power bills thanks to Mr. Sun.
