Finding & Hiring A Solar Company
The first step in installing solar panels is deciding what company will do it for you. Different companies offer unique products that might not be right for your home or yard. The panels might not be readily available, which could delay your installation timeline.
Before you choose a solar company, youll need to ask the right questions to learn about their products and how they install them. A representative from the company will need to visit your home to see how much shade you have and what type of panels will be best for your square footage and electrical needs.
Each visit can take a couple days to weeks. First, you have to decide if the company has what you need. Then, you have to schedule an appointment, which needs to fit into your schedule and the reps schedule. Afterward, the sales rep needs to write an estimate, then deliver it to you. Finding and hiring a solar company can be a test of patience.
If the solar company has what you want, and their price fits your budget, you might be able to decide right away. Otherwise, you could spend weeks or months trying to find the best company and product for your budget.
How Much Is A 5kw Solar Battery
A battery system for a 5kW solar unit costs generally between $1,300 to $2,000 per kWh. So for a 5kW system you might be looking at a total for the battery storage of around $7,000 to $10,000. The average time it takes to recover that initial outlay through reduced power costs is now below 10 years.
Most Powerful: Generac Pwrcell

Coming Soon: Your Personal Nanogrid
Sunnova is working on integrating traditional generators and demand-side management alongside its storage-plus-solar system to create a nanogrid that the company will then manage as a service provider.
Because conventional generators use fossil fuels, that solution isnt as clean as solar-and-storage alone, but it could offer higher reliability during extended outages.
Whatever solution customers choose, Berger said most recognize that climate change is worsening the impact of natural disasters, whether or not they live in California.
We see it all around the country and around the world, said Berger. This seems permanent this is not going to go away. Its not a one-time event, or two times. Its not just the wildfires its the hurricanes as well.
There’s no reason to sit in your house and wonder when the utility is going to shut off the power or when the power lines are going to go down. Frankly, thats a bit archaic, he added.
We should, as a society and not just in the United States, but globally be demanding better service. Right now, an increasing number of folks are able to go out there and get that better service.
Now in its fifth year, the Energy Storage Summit will bring together utilities, financiers, regulators, technology innovators, and storage practitioners for two full days of data-intensive presentations, analyst-led panel sessions with industry leaders, and extensive, high-level networking.
Structural Or Geotechnical Inspection
Time needed: days or weeks.
Depending on your local regulations, a structural engineer may need to come to your home to take a peek at your roof. If youÃ¢re going with ground-mounted solar panels, you may need to have a geotechnical engineer poke at the soil in your yard to determine what type of foundation will be required.
This is another step that doesnÃ¢t require much actual time from you, but usually you will need to be home to answer the door. Scheduling this can take several days or more out of the calendar.

What Happens In A Blackout
For most grid-connected systems, having a battery doesn’t necessarily protect you in the event of a blackout. You may still lose all power to your home, despite having solar panels producing power and a charged battery ready and waiting.
This is because grid-connected systems have what’s known as “anti-islanding protection”. During a blackout, the grid and any engineers working on the lines must be protected from “islands” of electricity generation pumping power unexpectedly into the lines. For most solar PV systems, the simplest way to provide anti-islanding protection is to shut down entirely. So, when it senses a grid blackout, your solar PV system shuts down and you have no household power at all.
More sophisticated inverters can provide anti-islanding protection during a blackout, but still keep the solar panels and battery operating so that the house has some power. But expect to pay a fair bit more for such a system, as the hardware is more expensive and you may need more solar and battery capacity than you think to run the house for a few hours during a blackout.
You should probably choose to allow only critical household circuits to operate in that situation, such as the fridge and lighting. That might require extra wiring work. A storage battery is likely to be drained very quickly if it also has to run things such as a pool pump or underfloor heating, which can draw a lot of power.

How Manufacturers Calculate The Loss Of Efficiency
As stated earlier, a crystalline solar panel may last up to 25 years. But how the manufacturers calculate the loss of efficiency during this period? In fact, companies producing these solar panels calculate .8% of efficiency loss per year.
After calculating the degradation or loss of performance at this rate, the operating capacity of a solar panel will reduce to almost 80% after 25 years. This is the efficiency standard that all the solar panels must hit.

Outside Factors Causing Degradation
Soiling is the most common factor, which affects the lifespan of a solar panel. Tiny dirt particles start to accumulate over the surface of a solar panel, reducing the amount of sunlight received by PV cells. Research has shown that a solar panel may loss 1% of its efficiency due to the loss of solar radiation.
Moreover, these panels are more likely to lose their power due to soiling when installing on the flat surface. Although it is quite easy to install solar panels on flat roofs, this results in the accumulation of more dust over the panels.
Weather also plays its role during degradation of panels, which is some cases turn out to be catastrophic.
A windstorm has the potential to damage your solar panel. After breaking from the trees, the branches may fall on the panels and trigger the degradation process. Hence, it is essential to install solar panels at a considerable distance from trees.
In addition, birds also pose a threat to the structural integrity of a solar panel. They prefer the dry area below the panel for making their nests. They even drop different materials over the glass, which inhibits the panelâs efficiency to a great extent.

Tip #: Keep Your Panels Clear Of Debris And Other Damaging Materials
An accumulation of dirt, pollen, leaves, and bird droppings can affect your solar panels efficiency. While rain is generally sufficient for cleaning your panels, you may want to consider a professional cleaning if you ever notice your panels arent working at their full capacity. You also want to make sure your panels arent under branches, as not only could the shade reduce output, but the branches could potentially fall in a storm and cause serious damage.
In case your panels are obstructed or damaged by any of these elements and you dont have the proper training or equipment to take further action, immediately contact your solar provider to receive assistance.
