Frequently Asked Questions

About Us

How long has LA Solar Group been in business?

LA Solar Group has 10 years of experience in solar installation and has been in business since 2012.

Is LASG fully licensed to install solar systems in CA?

Yes. We are CSLB C-10 (Electrical), C-39 (Roofing), C-46 (Solar) licensed and Electronics Technicians Association (ETA) certified.


Is Solar a proven technology?

Yes. Solar technology (including cells, modules, and inverters) are proven technologies – from both, functionality and long-term, low maintenance operation viewpoints. These same technologies allow the operation of satellites and unmanned vehicles on the Moon and Mars.

What is the difference between poly- and mono- crystalline solar panels?

Both types are manufactured from silicon wafers. The difference is that the mono-crystalline cells, which comprise the panel (or module), are made from a wafer consisting of only a single crystal; whereas, the poly-crystalline cell is composed of many mono-crystalline wafer pieces formed into a single cell. Compared to the poly-crystalline cells, mono-crystalline cells are more efficient, are darker or black in color (vs. bluish), have less degradation over time, and cost more. Each type has its pros and cons. For example, if enough roof space is available and high efficiency is not an absolute requirement, then installing more of the cheaper poly-crystalline based panels may be financially be better than installing fewer of the more expensive mono-crystalline panels. LA Solar Group carries both types and can review the financial and other aspects with you to arrive at an informed decision.

Site Evaluation

Do I need to be home for the Site Evaluation?

Although not necessary, we highly recommend that you are home in case we need to access internal areas, such as the attic, ask questions, and and we can discuss our findings

What is evaluated during the Site Evaluation?

The main items noted during the Site Evaluation are: roof direction, condition, shading, obstructions (e.g. vents) and measurements, electric main panel condition, sizing, and open breaker slot availability, and, if an attic run is being considered, attic access and suitability.

How soon after the Site Evaluation will the “results” be provided?

After the Site Evaluation is completed, we will analyze and provide an initial system design within one or two days, including any concerns or recommendations.


Can I cancel the contract after I sign it?

Yes. By law, you have the option to cancel the purchase contract within three (3) business days.


Who do speak to regarding payment?

Our Accounting Department takes customer payments. They can be reached at 818.435.3400.

When do I have to make a payment?

Payment breakdowns are in your solar agreement if it’s a cash purchase.

When will I get the invoice for my Solar PV purchase?

You will get a paid in full invoice when the project is fully paid and completed upon request. We can also send invoices along the way if requested showing the payments being applied.

Why do I have to pay my full balance before the system is turned on?

The full balance needs to be paid before the system is turned on. It covers Labor and Product as well. The payments are broken down in your contracts if it is a cash purchase. If you finance, the full balance is due when your city inspection has passed. Once the full balance is paid, we will be able to submit paperwork to utility company.


How will I know how may panels I need?

The number of panels required is based on many considerations and will be arrived at during the design phase. Some of these factors include: current usage, requirements, roof space, roof orientation, shading, panel efficiency, panel power, and financing.

What are the key criteria in the solar system design process?

The key considerations in the designing of a solar system include: geographic location, roof direction, roof pitch, roof space availability, roof type, roof condition, shading, current electric usage, offset amount desired, budget, local codes, HOA codes (if applicable), panel efficiency, panel power rating.

Can the customer have input into the solar system design process?

Yes. Some customers want to be fully involved, whereas some are interest just in the end result.


What are the key steps of the installation process?

The key installation steps for a roof installation generally include: Locating rafters, Installing roof mounts, railing, microinverters or power optimizers, panels, junction boxes, wiring and other electrical components, and finishing (e.g. stucco, painting).

Since the majority of the installation and workmanship related items involve the roof, what roof expertise does LASG have?

The most important aspect of installing a solar system on the roof, requires roofing expertise: working on the different types of roofs (e.g. shingle, tile, clay, metal), locating rafters so the mounts are properly secured, minimizing roof penetrations, properly flashing and applying adhesives to minimize damage and prevent leaks, and other aspects. LASG is a C-39 licensed roofing contractor. We have the expertise to properly install, as well as repair and re-roof.


Does anyone need to be home during the inspection?

Although you are not required to be home for the inspection, since most of the system is external, your presence may be required in case some of work is inside your home, for example, the attic.

What is the city inspection for?

The city will inspect the work to ensure it meets the city's installation and safety requirements related to solar, roofing, and electrical.

Do I turn on my system after the City inspection?

No. After the City inspection, your electric utility company may/will install a Net Meter and then grant you Permission to Operate (PTO). Only after the PTO is granted, can the Solar system be "turned on" and connected to the Grid.


Does the solar system require any regular maintenance?

Depending on the area you are living in, cleaning the solar panels of dust, dirt, and debris may be the only maintenance required. Again depending on your area, normal rainfall may be sufficient to clean your panels.


How do I know how much power I am producing?

It will only show the NET of production and usage, not on your utility bill.

How do I log into the Enphase monitoring system?

Once the envoy is installed, you don’t need to look at the display for getting data. You will receive an email with a web link which you can sign into to monitor daily/weekly/monthly production.

When will I receive the solar output monitoring software?

After the device is installed, within 72 hours the system will be registered and you will receive login information.

Warranties & Guarantees

What is the system performance guarantee? Will I be compensated?

LASG guarantees that the system will produce a minimum amount for energy (kWh) during the first and each of the following 24 years, assuming that the environmental conditions (e.g. shading) are the same as during the site analysis. In the event the system produces less energy than anticipated, LASG, at its sole option, will compensate you for the under produced energy amount or upgrade your system to enable full production.
