Do Solar Panels Affect House Insurance
In most cases, when you install solar panels on your roof, your insurance should cover you under the current terms. However, since a solar panel installation results in a change to the home structure, it is always advised to contact your current insurance provider before proceeding with the installation.
Its important to note that your home insurance may not include a cover for any damage by your solar panel or theft of the system. Therefore, its important to confirm with your insurance provider that your panels will also be covered.
Installing solar panels is a worthwhile investment for both homes and companies. They are a great step towards sustainability, reduce utility bills, and can even be a way for you to earn money back.
Homeowners Guide To Going Solar
Since 2008, hundreds of thousands of solar panels have popped up across the country as an increasing number of Americans choose to power their daily lives with the suns energy. Thanks in part to Solar Energy Technologies Office investments, the cost of going solar goes down every year. You may be considering the option of adding a solar energy system to your homes roof or finding another way to harness the suns energy. While theres no one-size-fits-all solar solution, here are some resources that can help you figure out whats best for you. Consider these questions before you go solar.

How does solar work?
There are two primary technologies that can harness the suns power and turn it into electricity. The first is the one youre likely most familiar with photovoltaics, or PV. These are the panels youve seen on rooftops or in fields. When the sun shines onto a solar panel, photons from the sunlight are absorbed by the cells in the panel, which creates an electric field across the layers and causes electricity to flow. Learn more about how PV works.

Once you have met with the installers and done all necessary site visits and planning, the actual installation of your home solar energy system will only take a few days of work. The exact time depends on a number of factors. For example, if you are setting up net metering, that process will tack on additional time until your panels are properly connected to the grid. Overall, while the decision process for solar panels can take some time, the installation timeframe is very quick and fairly simple.
How To Size A Solar Array
Using your average daily consumption in kWh
solar power system must be capable of producing to cover your needs
Peak Production Hours
The average number of peak production hours in South Africa is 5.5 hours per day in winter. It differs slightly from province to province, but this is the number we use.
Calculation
To determine your array size in watts, divide your average daily consumption by the 5.5 peak production hours.
EG: 30kWh per day / 5.5 hours PP hours = 5.46kWh array
NOTE: Add 2 more panels per 9.6kWh worth of storage to charge your battery bank.

How Do Solar Panels Work For Your Home
For most homes, solar panels for home means rooftop solar panels a solar array installed on your roof that generates electricity from the sun and helps you reduce your monthly spending on electricity. Solar panels work by converting light energy to usable electricity , which we can then use to power our homes and appliances. Solar panels save money over time on electricity costs and provide low-carbon, sustainable electricity.
Tip: Planning For The Future
Your electricity needs may grow in the future, so its essential to keep that in mind when choosing a solar system.
If you find that your array size is nearing the maximum DC input of the inverter you want to buy, you may want to consider sizing up. Alternatively, some solar inverters, like the Deye hybrids, can be paralleled, meaning you can add another one to your existing system.

What Percentage Of Your Home Can You Power With Solar Electricity
Ideally, the answer to this question would be 100 percent. However, although a solar panel system can theoretically offset all of your energy use, its not realistic to expect that level of panel production every day of the week. Manufacturers and installers often recommend that homeowners factor in a 25 percent fluctuation in generation when calculating their target for solar panel offset. The main reason for this: solar panels cannot operate at maximum efficiency all the time. There will be certain days when grid connection is necessary to fully cover your power usage. However, the beauty of net metering is that you can benefit from surplus production days and never pay anything to your utility while still relying on the grid for backup storage.

How Does It Work
An off-grid solar system works by collecting solar energy via the solar array that is made out of silicon photovoltaic cells that are linked together. Just how many and what type your solar panel depend on your location and your energy consumption.
To get maximum production, ensure that your solar panels are installed safely and strategically. Aside from collecting solar energy, it also converts it into DC power.
DC energy is then stored in a battery bank, which is group of batteries, that are wired together. It is recommended that you get a model that comes with a battery monitor. That way, you can effectively track and supervise the status of your battery bank as it provides you with information, such as the status, the charge and the maintenance.
Another way to protect your battery bank is by installing a solar charge controller. This allows you to regulate the voltage and current your battery bank receives from the solar panel. That way, you can protect your battery from damages.
After that, DC power is then converted into AC via your solar inverter. DC power is not usually used by your common appliances, hence, the need to convert it. A stand-alone inverter is highly suggested in off-grid solar systems.
How Many Panels Do I Need
One question that stumps many consumers new to solar is how many panels do I need to power my home? If you have the roof space, and the budget, we typically recommend that buy a larger system like a 5kW or 6.6kW system. Solar power systems this size deliver better value than smaller systems.
You can of course size your system based on your electricity usage. If you want to add battery storage, then this will also impact on how many panels you need.
- Shading or obstruction

Solar Photovoltaic Costs Considerations In Bc
The cost of installing solar PV systems has declined steadily over the last decade as a result of technology improvements and more efficient systems yielding a higher power output.
In B.C., a 1 kW solar PV system, south facing and tilted with no shading, will generate about 1,200 kWh per year or about 30,000 kWh over its 25 year lifetime. This is taking into account an industry average solar panel efficiency degradation rate of 0.5% per year.
At a turnkey installation cost of about $3,000, it would take you over 25 years to recoup your investment at today’s average electricity rates.
In remote locations where there is no grid to tie into for power, off-grid solar PV systems can be used to store power in batteries which can be used throughout the day or even at night. In B.C., off-grid systems make for a sound investment when installed in locations where alternative power sources such as diesel generators are required.
Batteries are obviously an added cost to an off-grid system and, depending on the type of batteries used, they require regular maintenance and/or replacement during the system’s lifecycle.

Compare Your Solar Options: Rooftop Vs Community Solar
Perhaps one of the most exciting aspects of the residential solar energy sector is the list of options for homeowners who want to go solar but do not have a suitable roof. Ground mount solar installations and community solar subscriptions are two common ways to access power from the sun without actually installing anything on your rooftop. Community solar involves connecting with members of a group or your neighborhood to share a solar system, while ground-mounted arrays are an easy way to own and install your own system while bypassing any roofing hurdles.
On Grid Home Solar System
This is the most common type of solar power system used in homes nowadays. On grid solar system also known as grid tie or connected solar system. It is a combination of solar panels and grid .
In this solar system, solar inverter converts the DC electricity produced by solar panel into AC electricity as you can see in the above diagram. Which can be used directly at home as well as business, grid tied systems do not work when the grid is not be there. If the electricity produced by the solar panel is more than your connected load then the surplus will be fed into the grid. Govt. will also adjust it in your next electricity bill through Net-Metering system.

Determine Your Solar Potential
There are a few things to consider when scoping out your home for rooftop solar. One factor to consider is the direction and tilt of your roof although this is not a hard and fast rule, rooftop solar panels perform best on south-facing roofs with a slope between 15 and 40 degrees.
Its also important to know how much sunlight your roof gets throughout the day. Solar panels need sunlight to produce electricity, so if your roof is shaded or otherwise obstructed by trees, chimneys, or anything else, that will impact how viable solar is for you.

What Is Solar Power For The Home
Homeowners who install solar power systems can receive numerous benefits: lower electric bills, lower carbon footprints, and potentially higher home values. But these benefits typically come with significant installation and maintenance costs and the magnitude of the gains can vary widely from one house to another.
This article will help homeowners make the financial calculations required to determine the viability of solar power in their homes.
Calculating Your Energy Production
The second factor you’ll need to consider in your calculations is the amount of energy your system will produce and when it will do that. This can be a very complicated calculation to make, even for experienced solar engineers. However, let’s run through the basics.
One of the most important considerations is the solar irradiation levels available in the home’s geographical location in other words, how sunny it is where you live. When it comes to using solar panels, being closer to the equator is generally better, but other factors must be considered. The National Renewable Energy Laboratory produces maps for the U.S. showing solar irradiation levels and the tools on its website provide detailed solar information for specific locations within the U.S.
Equally important is your home’s orientation: For rooftop arrays, a south-facing roof without trees or other objects obstructing sunlight maximizes the available solar energy. If this is not available, panels can be mounted on external supports and installed away from the house, incurring additional costs for the extra hardware and cables.
