TÜV SÜD Successfully Certifies Symtech Solar’s PV Power Generating Units and Solar Kits

Certificate No.  Z2 0004938 0001 Rev.00                                                                         


TÜV SÜD’s experts have developed a new comprehensive test and certification program to certify solar kits and PV power generating units. This new scheme will allow solar kit manufacturers to verify their products, and comply with international standards.

The TÜV SÜD certification scheme represents a milestone in the solar industry, since it is specifically designed and aimed to address a variety of quality as well as safety related issues associated to PV sub-assemblies. This will signify enhance safety and reliability of solar kits and PV power generating units in their actual application. Behind the development of this certification is TÜV SÜD’s Senior Product Specialists Alexander Krenz and Zhao Kai, as well as a test program in close cooperation with Symtech Solar’s co-founders, Geof Moser and Juan Castanon.

As for the main tests, they cover the entire functionality and ­­­compatibility of the systems with their key components, which are: PV modules, inverters, mounting systems, DC Disconnects, PV wiring, connectors and safety labeling. As a standard, each sub-component has been individually certified by TUV SÜD or equivalent certification agency prior to its inclusion in the new kit certification. Furthermore, each system has been verified for design and technical documentation, and includes production monitoring at the factory level. Production monitoring includes annual on-site inspections.

So how will this certification impact the solar industry exactly? Well, to start with, enhanced quality standards for solar kits will increase the protection of installers and system operators from potential risks that may occur from non-compliant design and solar system component selection. It will also ensure better functionality and performance for the life of the PV system for years to come. 

This new milestone of establishing a certification for PV system providers will initiate a trend towards continuously improving the safety criteria for PV system design and electrical installations throughout the industry. The current certification scheme will primarily follow the IEC 60364-1, IEC 60364-7-712 and will summarize all solar system certified components under IEC 61215, IEC 61730, IEC 62109-1, IEC 62109-2, PPP59029A, IEC 62446-1, EN 60947-3, EN 50618, EN 50521and other relevant standards.

Standards Include:

IEC 60364-1 provides the rules for the design, erection, and verification of electrical installations conducting to provide safety of persons, livestock and property against dangers and damage, which may arise in the reasonable use of electrical installations, and to provide for the proper functioning of those installations.  IEC 60364-1 applies to the design, erection and verification of electrical installations such as those of residential, commercial, public, and industrial premises (other inclusions apply) up to 1000VAC and 1500VDC.

IEC 60364-7-712 is part of IEC 60364 applies to the electrical installation of PV systems intended to supply all or part of an installation. The equipment of a PV installation, like any other item of equipment, is dealt with only so far as its selection and application in the installation is concerned. The object of this document is to address the design safety requirements arising from the particular characteristics of PV installations. DC systems and PV arrays in particular, pose some hazards in addition to those derived from conventional AC power installations, including the ability to produce and sustain electrical arcs with currents that are not greater than normal operating currents.

IEC 61215 covers the parameters which are responsible for the ageing of PV modules including UV, temperature, humidity, and mechanical loads.

IEC 61730 safety qualifications covers multiple parts including the design and construction requirements for the PV modules and application & safety class qualifications.

IEC 62109-1 and IEC 62109-2 covers the particular safety requirements relevant to DC. to AC. inverter products as well as products that have or perform inverter functions in addition to other functions, where the inverter is intended for use in photovoltaic power systems.

PPP 59029A testing covers mounting systems stability for various environmental conditions (heat, cold, dry, wet, etc.) and testing for corrosion resistance and long-term durability performance (endurance testing with outdoor field conditions, temperature change examination and moisture-heat examination).

IEC 62446-1 defines the information and documentation required to be handed over to a customer following the installation of a grid connected PV system. It also describes the commissioning tests, inspection criteria and documentation expected to verify the safe installation and correct operation of the system. It is for use by system designers and installers of grid connected solar PV systems as a template to provide effective documentation to a customer.

EN 60947-3 applies to switches, disconnects and fuse-combination units to be used in distribution circuits of which the rated voltage does not exceed 1000VAC or 1500VDC.

EN 50618 is a European Standard that applies to low smoke halogen-free, flexible, single-core power cables with cross-linked insulation and sheath. In particular for use at the direct current DC side of photovoltaic systems, with a nominal DC voltage of 1500VDC between conductors and between conductor and earth. Such cables are designed to be used with Class II equipment.

EN 50521 is applicable to Class A connectors (EN 61730-1) for photovoltaic systems with rated voltages up to 1500 VDC and rated currents up to 125 A per contact.

Explained In 30 Seconds - Hybrid Solar Energy Systems

- Explained In 30 Seconds -
Hybrid Solar Energy Systems 

This article is designed to simplify you're understanding of what a hybrid PV system is and how it works


A solar energy system that connects to the grid, has battery backup, and can operate in on grid and off grid mode

Major System Components:
  • Solar Modules
  • Hybrid Inverter/Charger (today these are integrated together)
  • Batteries
  • Mounting System
  • Wiring - PV and Battery
  • Safety Disconnects


On Grid

  1. Cheapest system cost
  2. Most simplified system
  3. Can sell power to the grid


  1. Works on and off grid
  2. Can sell power to grid
  3. 24/7 power supply



On Grid

  1. PV can't operate without grid
  2. Less overall power control


  1. More expensive then on grid
  2. More components to maintain


  • Solar Panels convert energy from sunshine into DC electricity
  • Solar electricity is transmitted to either
    1. The house loads
    2. Battery bank
    3. Back to the grid
  • If the grid shuts off the hybrid inverter becomes isolated from the grid and operates in off grid
  • The battery can send power to the grid or the loads


Lead Acid vs Li-Ion

Lead Acid - VR / AGM

How To Start A Solar Business

How To Start A Solar Business

As the solar industry continues to thrive, now more than ever are people eager to enter this market. Research, planning, and a strong business model can be the factor that makes or breaks your business. Below, are some factors to consider if you want to start a solar business that will succeed in the industry.

Start A Solar Business Installer

Do Your Research
While the solar industry continues to boost in growth, it continues to attract a growing interest. This is why it is critical to differentiate your solar company among its competition, and establish right away what makes you unique. By conducting market research, as well as searching some of the “needs” or “problems” of the solar industry, this can equip your company an opportunity to position itself. As the industry continues to grow and become more crowded, it it absolutely necessary to find your company’s niche in order to survive.
During this time, you can formulate your business model. While you should always believe in your vision, it is absolutely critical that your plan sticks to the numbers. To start a solar business, a successful one, lies in the foundation of its business plan. Establishing your target market, break even point, COGS, margins, are but few of many critical components your model should clearly outline.

Get The Paperwork Out Of The Way
To start a solar business, there are necessary steps you need to do to make sure your business runs smoothly. Do not procrastinate, and complete paperwork as soon as possible. Create a list to make sure you complete everything you need to do to get going. To help you out, we started the list for you:
Decide on what type of business you will be organized as:  LLC, Sole Proprietorship, C-Corp, S-Corp, etc. Whatever you choose, make it a priority to shield yourself from personal liability in the business.
Contact the IRS. You will need to apply for an Employer Identification Number in order to hire employees and establish a business checking account, as well as having an identification number. You can reach them by going on
Check to see if your state requires any licenses or permits.
Apply for certifications to establish credibility. For example, you can utilize  North American Board of Certified Energy Practitioners (NABCEP) and Green-e. To get these certifications, they are mainly centered around experience, training and passing an exam.
Register for state and federal taxes.
Get business insurance.
Set up business accounting practices/services.
Ultimately it is your responsibility to make sure your business completes all necessary paperwork to comply with federal and state authority.

Grow Your Business
In order to make money, you must spend money. Which is why that you must account for not only the initial investment but the reoccurring expenses as well. Common ongoing expenses include:
  • Payroll
  • Price of ordering panels from a distributor for each job
  • Marketing
  • Business insurance coverage
  • Expense towards the energy company on behalf of leased customer accounts
  • Office rent
  • Solar paneling delivery vehicles
  • Ongoing employee training
  • License maintenance
Accounting all necessary expenses, you should budget how much money left over you have to spend on developing your brand. Branding can significantly help your business if done correctly, and can really help develop an identity that customers can associate with your company. Although branding can be expensive, there are some ways to save in this department, such as hiring interns, utilizing free online design platforms, and devoting time to growing social media platforms along with other free online applications.
Also, another way to cut expenses is to think of creative ways to reach your customers. By thinking out-of-the-box, your solar company does not have to be limited to relying on customers to find them online. Trade shows, attending home shows, and getting involved with the local community are few of many ways that you can find and create meaningful, long-lasting customer relationships. Because at the end of the day, the relationships that your business creates with its customers is what dictates the longevity of your business.

Consider Creating A Partnership
Let’s face it, to start a solar business, although can be lucrative, is time-consuming, complicated, and capital-intensive. While it is possible to build a company from scratch, many solar businesses initially do not succeed due to inadequate planning, budgeting, or lack of knowledge in the industry.
This is why utilizing a partnership can be the catalyst towards helping your solar company financially succeed. With many years of experience, your partner has the knowledge and capabilities in the solar industry that you most likely lack in the beginning stages of your business.
