What Are Solar Panels
Solar panels capture and convert the energy of sunlight to power your home. They can store excess energy in batteries or feed it back into the electrical grid, resulting in credits to your utility account. Most residential solar panels are roof-mounted, although they may also be set up in a field or other area that gets direct sunlight.
Panels come in an array of sizes and power levels. Most residential rooftop solar panels are about 3-1/2 feet by 5-1/2 feet, and produce about 250 to 300 watts per hour of sunlight. A 300-watt panel exposed to five hours of sunlight would produce 1,500 watts, or 1.5 kilowatts . Solar panel systems are described by their total hourly production, so an array of ten 300-watt panels is known as 3 kW.
Benefits Of Investing In A 4kw Solar Panel System
Are you in doubt whether it is a good idea to invest in a solar power system? It is true that buying 4kw solar panels implies a considerable investment, but this will guarantee that you will produce your own and clean energy, and will also save money in the future. As with any big investment, one should think of solar panels from a long-term perspective.
Even though it is cheaper today to pay your bills and get electricity from the national grid, this will not remain the same in the future. Firstly, because the price of fossil fuels will undoubtedly grow, therefore pushing the prices of electricity produced from such sources.
Secondly, as more people are switching to green energy, economies of scales are leading to lower prices in the respective technologies. In the next few years, solar panels will be cheaper, and more effective.
Additionally, as governments are pressured to take actions in order to tackle climate change, there are many incentives and solar panel grants that make green investments financially convenient.
Different Solar Panel Cost For A 2500 Square Foot House
Above calculations are for monocrystalline. For a 2500 square feet house, installation of monocrystalline panels would cost between $17,000 and $36,400. Lets compare all three types of panels i.e. monocrystalline, polycrystalline, and thin films.
As polycrystalline panels are 20% cheaper and 20% less efficient as compared to monocrystalline so price range will be as follows: * 400W per panel * = $16320 * 400W per panel * = $34944
As thin film panels are 50% less efficient as compared to monocrystalline and cost $0.75 to $1 per kW so price range becomes: * 400W per panel * = $7650 * 400W per panel * = $15600

Energy Independence: Another Exception
Although it is possible to do so, it is not realistic at this time to try to be completely independent and disconnected from Hydro-Québecâs power grid unless you have a very energy-efficient home and keep your energy consumption to the bare minimum. The main challenges you face are the power ratings of certain energy-hungry appliances and the space required to install solar panels.
For example, you would have to have up to 70 solar panels to generate enough energy for an average-sized house. And 70 solar panels would be the equivalent of two-thirds of a tennis court, often larger than the surface area of a roof.

How Much Money Can I Save And Earn
A correct number cant be set as the sun rays that your 4kW solar system will collect will vary throughout the year due to weather conditions. To make sure that you are getting the most out of sunlight, you must consider the placement of the system before installing it.
For instance, the angling of your roof can increase or decrease the efficiency, if your roof is completely North facing your panels will have significantly reduced capabilities. Remember that if you want to increase your earnings, you will have to save energy. Dont leave all appliances working or on standby when you are not using them.
For the installation, you will need 28 m2 of free roof space and around £7,000 for the purchase and installation. The first year you are looking at around £700-800 return, which means that the system will pay for itself in approximately 9.5 years and for a 20 year period you are looking at around £5,000-6,500 pure profit.
Steel Shingles And Tiles
There are several common types of steel roofing. Galvanized steel, which is coated with zinc to deter corrosion, is a popular choice for its strength and durability. A cheaper alternative is Galvalume, which is aluminum-coated steel. On the high end of the scale is stainless steel, which is a rare but striking choicethe Chrysler Building, for example, is roofed with stainless steel.
A 100-square-foot Galvalume panel costs between $75 and $250 and installs for a total of about $5.50 per square foot. Galvanized steel, which is a bit more expensive, runs about $3.35 to $4.25 per square foot, and materials plus installation come out to about $10 per square foot, or $17,000 to $25,000 total. Stainless steel is quite a bit more expensive at $10 to $16 per square foot for materials and as much as $15.50 more per square foot for installation.

Build Your Solar System With Future Needs In Mind
Because solar systems are designed to last about 30 years, its a good idea to consider your future needs before designing your array. If you are planning any significant changes at home that could impact your electricity use, keep those in mind.
Are you planning an addition to your home? This could have a huge impact on energy use due to air conditioning or if there will be additional occupants.
Do you plan to get an EV soon and charge at home? Often, EV owners will add a few extra solar panels to charge their vehicles with solar energy.
Are you swapping out any energy-hogging appliances or converting from gas to electric appliances? For example, replacing a gas clothes dryer with an electric one will increase your electricity consumption. The same is true for replacing a gas stove with an induction range.
Conversely, replacing an inefficient water heater with a hybrid water heater can reduce your energy consumption. Even installing a water-efficient washing machine could conserve energy if you currently use a top loader and wash clothes in hot water.
In some cases, you can plan to add additional photovoltaic capacity later. For example, if you use microinverters or oversize the central inverter and save space on the roof, you can easily add solar panels in the future. Also, some solar batteries are relatively easy to add to an existing solar system.
When To Install Solar Panels
Contrary to popular belief, winter is actually the best time to install solar panels. There is simply less demand for this service in winter, so the installation should cost less as a whole. Even if you live in a region that tends to be cloudy and/or chilly, your solar panels will still be able to generate energy and in some cases, will even generate more energy than they would in warmer months.
Installing solar panels during winter is, in addition to being cost-effective, efficient. With solar installation companies doing fewer jobs in the off-season, your panels are likely to be installed faster, and will be up-and-running in no time.

Other Reasons To Go Solar
Saving money is just one reason people go solar, notes Robert Stoner, deputy director for Science and Technology of the MIT Energy Initiative . I think most people who invest in residential rooftop solar simply want to be part of the transition, and to a lesser degree to be seen to be, he says. Nothing wrong with thatSome, like me, own homes my weekend home is at the end of a five-mile-long barrier beach that simply dont have the option to have grid electricity. Stoner says his solar system, which includes a bank of lead acid batteries, provides all of his electricity, And it brings me a lot of joy! Some of that comes from the feeling of independence I get, and some of it from getting to experience the miracle of electricity being produced from the sun.

Tesla Solar Roof Cost
A Tesla solar roof costs $22 to $45 per square foot, which includes the solar roof tiles, a Powerwall, roof and site repairs, and complete system installation. A 9.45 kW solar system installed on a 1,800 square foot roof costs between $39,600 and $81,000.
On average, solar shingles cost up to $8,000 more than installing a new roof with traditional PV solar panels. Glass-faced solar shingles mimic the appearance of a tiled roof and cover more surface area than mounted PV panels to catch more sunlight.
Solar tiles have a lower efficiency rating in producing electricity. They may not last as long as PV panels because their design doesnt allow much room for ventilation, which can lead to overheating.
How Much Do Solar Panels Save
Though solar panels cost money upfront, they are certain to save you money in the long-term. The question of how much solar panels will save you depends on a number of factors, including the hours of daily direct sunlight available to the panels, the angle of your roof and the size of your solar panel system. The most important factor, though, in determining how much money solar panels will save you, is simply your local electricity rates.
In order to determine how much money your solar panels will save you each year, calculate how much you spend on electricity annually . Then, determine what your current utility rate is, keeping in mind that utility rates tend to increase 2.2% or so each year .
Use an online calculator to estimate your annual savings by plugging in information like your location, energy usage and the current average price of solar panel installation in your area.
A common misconception is that solar panels will eradicate your electricity bills altogether. While this is sometimes the case, solar panels will significantly reduce your electricity bill each month, and are worth the investment as a whole.
