FAQ Guide for solar panels

When there is a question, there is an answer ,LESSO Always offers more than expect

Photovoltaic panels are an important part of the home power generation system, this article will give readers answers to some common applications of photovoltaic panels from the actual application as well as the knowledge of installation

Can 2 solar panels power a house?

2 solar panel system power range from 800w- 1200w, it is quite difficult to power a family house, but it can be installed on balcony as a small solar system with micro inverter, it can power a few of home devices and reduce the power consumption, when there is excess electricity, it also can sell to the grid to get a part of revenue, makes a lower monthly bill

How long do solar panel last?

Normally the good quality solar panel warranty range from 5-10 years. Some suppliers offers longer warranty, which ensure a higher quality ,such as Lesso solar, for normal specification is 12 -15 years

What type and size of PV panels do you have?

Currently Lesso provides high quality and cost-effective monocrystalline silicon photovoltaic panels, the quality and efficiency up to 21% is comparable to first-tier brands with a more reasonable cost. There are 2 choices widely used in the project: 410w and 550W to choose from, which meet the demand of home and commercial projects

Photovoltaic panel installation mounting bracket

2 types of installation for home projects: Roof pitched and ground,it fix by the rails, connectors, pins or cuff, triangles and other steel pare parts.

What is the connection way of the photovoltaic panels? Parallel or Series

In home energy storage systems, PV panels are only connected in series. For example, 16pcs of 410w photovoltaic panels are connected in series to form a 6.4kw PV array.
However, in large PV projects, the panels need to be connected in series as well as in parallel.
550w 18 series and 7 parallel to build a 69kw PV array

How to calculate the area is needed for PV panel installation?

1kw PV covers 4 Square footprint,and we need extra aisle for checking and maintain,For example
5kw PV at least need a 25-30 Square space to install

How do I calculate how many solar I need ?

First of all, calculate the total consumption of your home, for example it takes 10kwh , and the Average sunshine is 5hours in your city, it means you need at least 10kwh/5h=2kw solar to cover the loads daily operation, by the way ,you need to take the budget , and installation space into consideration to determine how many solar you need

How to calculate the daily electricity generation from photovoltaic panels?

For example : One 410W panel in a 5 hours sunshine area can generate 0.41kw*5hrs=2kwh/day
so 10pcs of 410w panel can generate 20kwh/day

What does the efficiency of a photovoltaic panel mean and what does 21% efficiency mean?

The higher the efficiency of the photovoltaic panels, the higher the power generation per unit area, high efficiency components means higher technical requirements, 21% efficiency means that the power of 1 square photovoltaic panels is 210w, while the power of 4 square panels is 820w

Are PV panels protected against lightning strikes?

Yes, we have devices to avoid the damage from the strike

What is a combiner box and do I need to use it?

Household photovoltaic systems do not need to use the combiner box

Only in large photovoltaic projects will the combiner box be used, the combiner box is divided into 4 into 1 out, 8 into 1 out, and other different types, respectively, can be a number of series lines combined together

If I can get customized service for photovoltaic mounts? What information is required?

Sure, the Bracket plan are customized, we will offer drawings according to the project situation
PV bracket plan need info as follows:
1 Roof or ground material
2 Roof beam material, beam spacing
3 Country, city and angle of installation
4 The length and width of the site
5 Local wind speed
6 Photovoltaic panel size
After collect the information from customer, solution provider will offer a complete solution for it
