1. What aspects can I start from to better compare solar system quotes and make a choice?

To get a satisfactory solar system quote, you need to consider a number of aspects before making the right choice. In general, these aspects can basically be categorized into four main groups, namely, module brand and performance, system size and configuration, warranty and after-sales service, and payment content and payment method. These aspects are described below:

1.1 Branding and Performance

First of all, the brand can add a guarantee to the product, but accordingly it affects the offer of the product. For example, JA Solar market share in Europe is very high, an average of about 20%, and in the United Kingdom and the Netherlands share of up to 65% and 55%, respectively, and therefore in 2023 was awarded the EUPD Research “Europe’s top brands” honors, but the brand’s products than the same type of products priced 5% to 10% higher than the same type of products. However, the brand’s products are about 5% to 10% more expensive than their counterparts.

This example also shows that many well-known brands are recognized by consumers for the quality of their products, and these brand manufacturers have a lot of experience in manufacturing solar equipment, which can meet your requirements, but the price of branded products will be higher, which you need to take into account when comparing the price of solar energy systems.

Then there is the performance of the solar equipment. This is easy to understand, for example, in the same wattage of solar panels, one has an energy conversion rate of 25% and the other has an energy conversion rate of 30%, then it is obvious that the latter one has a stronger performance, but, accordingly, the quotation of the latter one will also be higher. Like solar inverters, solar battery and solar convergence boxes and other equipment is the same reason, you need to pay attention to the specific performance parameters of each device when comparing the offer of solar energy system.

1.2 System size and configuration

You need to consider the size of the solar system when comparing the offer of the solar system, such as a 5kWh solar system and an 8kWh solar system, etc., just the solar panels, an 8kWh solar system is much higher than a 5kWh solar system, not to mention the solar batteries, solar inverters, cables, and other equipment, therefore, the larger the size of the solar system under normal circumstances, the more the solar system is, the more the solar battery, and solar collector boxes are, and the more the solar system is configured. Under normal circumstances, the larger the size of the solar system, the higher the offer will naturally be, of course, the output of solar energy will also be more.

The internal configuration of the solar system will be the same size of the two solar system quotes are different, the internal configuration includes solar battery, solar monitoring system and solar power protector, these will play a certain role in the solar system, you are in the comparison of solar system quotes, be sure to confirm that these internal configuration is included.

For example, if you have two solar systems with the same 8kWh capacity, one using lead-acid batteries and the other using lithium iron phosphate batteries, and the basic parameters of the two batteries are the same, then the solar system using lithium iron phosphate batteries will naturally be quoted at a higher price. Therefore, the configuration of the solar system is very important when you pick the right solar system offer.

1.3 Warranty and after-sales service

The warranty period of the same product sold by different manufacturers will vary and so will their quotes. For example, BSLBATT manufactures a wide range of models of solar cells that offer up to 12 years of warranty, which is about 2 to 4 years longer than the same type of solar cells, but the solar cells manufactured by BSLBATT are quoted at a price that is about 5% higher than the same type of solar cells.

After-sales service is to ensure that you can use the equipment properly in the future, and that any problems with the equipment can be dealt with in a timely manner. For example, some solar equipment manufacturers can promise you that if your equipment is damaged within the warranty, the business will provide you with shipping and free repairs, which will inevitably lead to better after-sales service and higher prices for their products than their counterparts, which in turn leads to higher solar quotes.

In order for you to get a satisfactory solar offer, you should make clear to the manufacturer of the warranty content (including warranty duration, warranty conditions, etc.) and after-sales service content, understand these, and then according to your own situation to comprehensively consider the offer of solar energy systems, which will increase the probability of you picking to the satisfaction of the solar energy system offer.

1.4 What is included and how to pay

After you get a quote for a solar system, make sure you know what is included in the quote, otherwise you may need to spend extra money to pay for what is not included in the quote for the solar system, which is very detrimental to your ability to choose the right quote for the solar system.

For example, if you choose a solar energy system, but the solar energy system does not include the transportation cost of the solar energy system and the installation cost of the solar energy system, even if the solar energy system may be slightly lower than other solar energy systems of the same type, but you need to spend time and energy to deal with these things, and in the end, the combination of the quote did not make clear what is included! Not only does it affect your judgment, but it may also happen that you end up paying more than other types of solar systems.

Then, you need to find out from the manufacturer about the payment options, such as cash on delivery, installment payment, and payment after the product has been used for a while without any problems.

For example, if you need to choose installment payment for two solar systems with the same offer price, it may be that one manufacturer stipulates that you need to pay 1% interest on the installment payment of the solar system while another solar manufacturer stipulates that you need to pay 1.5% interest on the installment payment, then the result will be obvious and you should choose the former. In short, whichever payment method you choose, it is important for you to know the specific details of the payment method to prevent you from losing out.

2. What are the ways you can get a quote for a solar system?

There are many ways to get a quote for a solar system, such as getting a quote online using an internet device such as a cell phone, contacting a solar manufacturer for a quote, and asking a friend or neighbor for a quote. To get a quote online, many manufacturers will have a website for their products. All you need to do is go to their official website and fill in the information about your area, the size of the product you need, and the performance of the product, and you will be able to get a quote for a specific solar energy system.

3. Summary

With the understanding of solar energy system quotation, you can pick the one that suits you the most among a number of solar energy system quotations. All in all, the key to picking the right solar energy system quote is to consider all aspects, scrutinize them carefully, and finally make a choice. Want to get a satisfactory solar system quote?
