Frequently Asked Questions

About Purus Energy

How does a quote from Purus Energy differ from other solar providers?

Our quotes give you a complete rundown of what your system will be like, including system size, panel types, and other adders you may want to include in your package. With other providers, many variables get lost in the process when fitting your home for solar. Homeowners end up paying extra for inflated prices or unnecessary fees for either small systems or low-quality panels. Getting a quote with Purus Emergy will give you a full view of exactly what you’ll be paying for when getting solar.

Why is it important to have your house system sized correctly before getting started?

There are many variables that determine what size system will benefit you the most. The wrong size system can increase cost or drastically reduce their Return on Investment.

  • Too big of a system: cost goes up, more panels than necessary, more holes being drilled
  • Too small of a system: not enough production, increasing true up bills, much longer ROI period
What brands do you partner with?

We partner with all the major panel brands including SunPower, SunRun, Vivint, and all the major solar finance companies.  Our goal would be to help you get the right system at the best price.

Going Solar

How do solar panels work?

The panels are installed on your roof or property will absorb the sunlight that hits it and turns it into energy. This energy is then turned into electricity that can be used in your home to power any electrical appliances you use. Surplus energy that your panels produce will either be sent to your utility company (if you’re still on the grid) or into a storage battery (installed into your home’s solar system) which can be used during power outages or any other emergency.

Is going solar expensive?

The most expensive part of going solar is paying for your system’s equipment. However, with many financing options and available incentives, Purus Energy can install the solar panels at little to no upfront cost. Plus, the amount of money you’ll save on your electricity bill by going solar will make all the initial costs worth it.

 

Is my roof a good fit for solar?

Ideally, a south-facing roof is best for going solar. Since the sun rises in the east and sets in the west, a south-facing roof will receive the most amount of sunlight throughout the day. However, if roof installation is not possible, you have the option to install solar panels on the ground where space is available.

Are there any rebates and incentives for going solar?

Right now the government is providing a federal investment tax credit (ITC) for those who own residential OR commercial solar systems. A tax credit is a dollar-for-dollar reduction in the income taxes that a person or company would otherwise pay the federal government. The solar ITC is only available until December 31, 2023. It can deduct up to 26% off your system, with this percentage continuing to drop after 2020. All major types of solar technology (photovoltaic, solar heating & cooling, and concentrating solar energy) are eligible to receive this tax credit.

Many states, counties, and municipalities and utilities may offer other rebates and incentives for solar technology owners. The Database of State Incentives for Renewable and Efficiency (DSIRE) has a complete list of solar incentives by state, as well as extensive information on solar policies across the U.S.

What is net metering?

Net metering (also known as Net Energy Metering or NEM) is the billing system that utility companies use to credit solar system owners for the unused electricity generated by their solar panels. When your solar panels produce more energy than you use, the surplus energy will be sent back to the grid in exchange for credits. When your panels are underproducing, you will pull electricity from the grid and use the credits to offset the charges.

What are the rate increases with PG&E?

PG&E has filed for a General Rate increase with the Public Utility Commissions to approve a 12.8% rate increase each year from 2020 – 2022.  This will be their 4th major rate increase since 2009.

About Your System

How long is the warranty on solar panels?

The majority of solar panels include a 25-year long warranty, also known as a performance guarantee. Most of the time, this means your panels have a guaranteed electrical production of 90% of rated power output for 10 years and 80% for 25 years.

Do the solar panels degrade over time?

On average, solar panel output degrades by 0.8% each year. This rate may vary depending on the panel brand you buy. Premium manufacturers such as SunPower have degradation rates as low as 0.3%. Solar panel technology is constantly improving, so degradation rates below 1% are common throughout the industry. Many newer panels only have a 0.5% decline in energy output every year.

How long will my solar system last?

A typical system will last at least 25 years. This is the industry standard warranty for Tier 1 manufacturers, but most systems will last longer than 25 years. Warranties usually guarantee panels will work above 80% above their rated efficiency after 25 years. A study by NREL shows that the majority of panels will still produce energy after 25 years, albeit at a slightly reduced production rate.

What happen to my panels on a cloudy day?

Sunny climates are perfect for solar energy production. Most of the United States is far from being as sunny as California or Hawaii, but solar panels are still installed across the country. If you live in an area where it is not sunny year-round, you can still produce your own power with a solar energy system part of the time. Living somewhere where there is not a lot of sun should not scare you from getting solar. In the end, producing some of your own power is better than producing none at all.

Do solar panels work during a power outage?

This answer depends on the solar system you decide to purchase for your home. Panels installed on your roof or property will continue to create electricity during a power outage as they normally would. However, if your home is tied to the grid, you will not be able to use this power during an outage since your utility company will shut off your home’s electricity. If you have a backup battery system, then you will be able to use power during an outage.

Do I need to clean my solar panels?

Making sure your panels are clean is one responsibility that comes with having a solar system. Your panels need to be exposed to sunlight in order to produce energy, so any dust or debris on your panels could reduce the amount of sunlight your system receives. Having clean panels is essential to maximizing your system’s production, but it does not need to be done often. Unless you live in an area that has high amounts of dust, smog, or sand blowing around, occasional rainy days are enough to keep your panels clean.

If you live in an area where there is a lot of dust or pollution, here’s how to clean your panels safely and effectivelyWhen cleaning your solar panels, the most important consideration to keep in mind is that scratching or damaging the glass in any way will reduce a panel’s energy production. It’s best to approach panel cleaning the same way you might clean your car. Dish soap and warm water applied with a soft sponge or cloth is the safest and easiest cleaning method. It may also be helpful to use a squeegee to remove dirty water. Remember – avoid damaging or scratching the glass at all costs!
