Table of Contents arrow down

Solar power offers a greener alternative to traditional energy sources and presents significant long-term cost savings. However, the process of selecting and installing a solar system involves numerous considerations to ensure that it aligns perfectly with your specific needs and objectives. This is where EnGoPlanet steps in. As a leader in solar energy solutions, we understand that venturing into solar installations can be overwhelming, especially for those new to the concept. To assist you, we have compiled a list of essential questions that you should ask your solar installer. Our goal is to equip you with the right information, helping you make informed decisions that maximize your investment. Whether you aim for a cost-effective solar solution for your home or want to implement a larger-scale commercial project, these questions will serve as a critical tool in your decision-making process.

What to Ask Your Solar Installer

You should ask your solar installer many questions before you decide to hire them and which solar lighting solution to go for, whether you are considering residential solar street lights or commercial options. We have grouped the questions into relevant categories to make it easier for you to find the information most relevant to your concerns and help you prepare for discussions with solar installers. Each category of questions addresses a fundamental component of solar system installation and operation.

Battery specs and system compatibility concerns are only some of the questions to ask your solar installer.

You should ask the solar company representatives questions concerning:

  1. Battery technology
  2. System requirements and compatibility
  3. Cost and maintenance
  4. Safety and disposal
  5. System capacity and efficiency
  6. Installation and permissions

Battery Technology

Understanding the type of battery technology used in your solar system is essential as it affects the system’s efficiency, lifespan, safety, and overall performance. Different technologies offer various pros and cons, making some better suited for specific needs and environments.

Here is what you need to know:

  • What battery technology does the solar system use?
  • Why are you recommending it to me? (Including advantages/disadvantages like charge/discharge efficiency, weight, size, life expectancy, safety considerations, etc.)
  • What is the predicted lifetime of the batteries? (Including charge-discharge cycles and years)
    What’s the usable storage capacity in kilowatt-hours (kWh)?
  • What is the charge-discharge efficiency?

System Requirements and Compatibility

This category ensures that the new solar system is compatible with your existing setup (if any) and meets your specific energy needs. Questions about system compatibility, power backup during outages, and potential for future expansion are crucial for smooth integration and operation.

Here is what you need to ask:

  • Does the solar system require the replacement of my existing solar inverter? [if you have one]
  • Will the solar batteries need mains electricity to charge at any time?
  • Can I add more batteries at a later date to increase the storage capacity?
  • Will the system give me power during a main power cut?
  • If the system does provide power during a power cut, how will this work in practice (will I have to re-wire the house to achieve this)? And what will I be able to run?

Cost and Maintenance

Cost considerations and maintenance requirements are vital for long-term financial planning. Knowing the cost of replacement parts, maintenance needs, and overall lifecycle costs helps in evaluating the financial viability of the solar system.

Cost and maintenance questions are crucial.

Ask your solar installer the following:

  • How will I know that the batteries are nearing the end of their life?
  • What’s the cost of replacement/additional batteries?
  • Can I buy replacement batteries from anywhere, or do I have to buy a special type from the original system manufacturer?

Safety and Disposal

Safety is paramount in any electrical installation. Understanding safety considerations, particularly in battery management and disposal, is crucial to prevent accidents and ensure environmental responsibility.

You must know the answers to the following questions:

  • Are there any special considerations in terms of battery management/maintenance or storage location I need to be aware of?
  • How would I safely dispose of used batteries at the end of their life?

System Capacity and Efficiency

These questions help you understand the real-world performance of your solar system. Knowing the system’s usable storage capacity and efficiency helps assess how well it will meet your energy demands.

Here is what you should know:

  • What does the useable storage capacity in kWh mean in practical terms? (Indicating what type of appliances could be operated and for how long)
  • How does the solar system perform under different weather conditions, such as cloudy or rainy days?
  • Can the system maintain a consistent energy output throughout the day and across different seasons?
  • Is the system scalable to meet increasing energy demands in the future?
  • How is the system optimized for the specific geographical and climatic conditions of my location?

Installation and Permissions

Finally, this category addresses the administrative and logistical aspects of solar system installation. Understanding the need for permissions, the potential impact on existing electricity arrangements, and monitoring capabilities is essential for a compliant and efficient installation. This is important for residential and municipal solar street lights equally.

Ask your solar installer the following questions:

  • Will the system affect my generation meter reading/FIT income at all?
  • Does the system incorporate a means of monitoring electricity in and out?
  • Do I need to get any permissions/notify anyone before having a battery storage system installed? (Including Distribution Network Operator, Ofgem, and the local council)

Maximizing Solar Energy Efficiency: Additional Considerations

In addition to the categorized questions to ask your solar installer, it’s essential to understand some key aspects of solar energy systems that impact their efficiency and effectiveness. Here are additional considerations to keep in mind:

  • Annual Demand and Cost Estimates: It’s crucial to ask for an estimate of the annual demand and cost. This helps in understanding the financial implications of the solar system over time.
  • Offpeak Electricity Charging: Inquire whether the system can be programmed to charge from cheaper off-peak electricity. This can significantly reduce operating costs.
  • Nominal vs. Usable Capacity: Understanding the difference between the nominal and usable capacity of batteries is important. Most types of batteries should not be 100% discharged as this shortens their life. For example, a battery quoted as 500Ah at 12V might appear better than 200Ah at 48V, but it’s actually smaller (500 x 12 = 6kWh; 200 x 48 = 9.6kWh).
  • Depth of Discharge: Be aware of the allowable depth of discharge for your batteries. For instance, a 3kWh battery with an allowable depth of discharge of 80% would effectively provide 2.4kWh, which could supply 200W of lighting for approximately 12 hours.

Turning Solar Plans into Reality

As you move forward with your decision to install a solar energy system, it’s important to have a structured approach. Consider creating a checklist with the discussed questions to take with you to your solar installer. This ensures that you address all the relevant aspects and make the most of your consultation.
