SOLAR PANELS

These FAQs cover various aspects of going solar, from the benefits and costs to longevity, maintenance and purchasing options.

  • Solar energy is renewable, reduces electricity bills, has low maintenance costs, reduces carbon footprint, and can increase property value.

  • The cost varies depending on the size of the system, location, and the type of panels used, but average costs range from $15,000 to $25,000 for residential systems.

  • Most solar panels have a warranty of 25-30 years, but they can last longer, typically up to 40 years, with proper maintenance.

  • Yes, with the right size and configuration, solar panels can generate enough electricity to meet the needs of an entire home. However, this depends on the household's energy consumption and the local solar potential.

  • Factors include the angle and orientation of the panels, shading, temperature, and the type of photovoltaic cells used.

  • While some DIY kits are available, it is generally recommended to have a professional installation to ensure safety, compliance with local regulations, and optimal performance.

  • Many governments offer incentives such as tax credits, rebates, and grants to encourage the adoption of solar energy.

BATTERY STORAGE

Storage batteries offer many advantages, particularly given California's unique environmental, economic, and regulatory conditions. Here are some FAQs:

  • A system that stores energy generated from solar panels for later use, typically consisting of batteries, an inverter, and a control system.

  • Solar panels generate electricity, which is either used immediately, sent to the grid, or stored in batteries for later use, especially during peak hours or power outages.

  • Reduces electricity bills, provides backup power during outages, increases energy independence, and maximizes the use of solar energy.

  • Costs vary depending on the size and type of the system, typically ranging from $10,000 to $20,000, including installation.

  • Yes, incentives such as the Self-Generation Incentive Program (SGIP), federal Investment Tax Credit (ITC), and various local rebates can reduce costs.

  • A California program that offers rebates for installing energy storage systems, aimed at reducing greenhouse gas emissions and increasing energy reliability.

  • It depends on your energy usage, the size of your solar panel system, and your backup power needs. Typical systems range from 5 kWh to 20 kWh or more.

  • While it is technically possible, most systems are designed to complement grid use rather than replace it entirely. Going off-grid requires a significant investment and careful planning.

  • Solar batteries typically last between 10 to 15 years, with warranties usually covering 10 years.

  • The most common types are lithium-ion batteries, including lithium iron phosphate (LiFePO4) and lithium nickel manganese cobalt oxide (NMC).

  • It can lower your bill by allowing you to use stored energy during peak rate times and reducing reliance on grid electricity.

  • Yes, they reduce reliance on fossil fuels and help integrate more renewable energy into the grid, although the manufacturing and disposal of batteries have environmental impacts.

  • Yes, most existing solar panel systems can be retrofitted with battery storage, but it's important to check compatibility with your current setup.

  • A solar battery storage system can provide backup power during outages, depending on the system's capacity and how much energy is stored.

  • Most systems come with monitoring software or apps that allow you to track energy production, usage, and battery status in real-time.

  • Yes, various financing options, including loans, leases, and power purchase agreements (PPAs), are available to help spread out the cost.

  • Minimal maintenance is required, but regular inspections and monitoring can help ensure optimal performance and longevity.

  • Most homes can accommodate a solar battery storage system, but it's important to assess space, electrical infrastructure, and solar potential.

  • Consider factors such as energy needs, budget, available incentives, system compatibility, and warranty terms. Consulting with a professional, such as Pure Powr Pros™ can help make the best choice.

  • Yes, when installed and maintained properly, solar battery storage systems are safe. Modern systems include safety features to prevent overheating and other issues.

UP-GRADES

Here are some frequently asked questions (FAQs) about adding solar panels and/or storage batteries without losing your Net NEM 1.0 or NEM 2.0 status:

  • Answer: NEM 1.0 and NEM 2.0 are versions of Net Energy Metering programs that allow solar energy system owners to receive credits for the electricity they add to the grid. NEM 1.0 was the original program, and NEM 2.0 includes additional charges and fees.

  • Answer: Yes, but there are specific rules and requirements to maintain your NEM status. It's important to follow these guidelines carefully to avoid being transitioned to a newer, potentially less favorable NEM program.

Solar Panel Additions:

  • Answer: Generally, you can increase your system size by up to 10% of the original system capacity or add up to 1 kW, whichever is greater, without losing your NEM status. Specific rules can vary by utility provider.

  • Answer: Yes, you will need to apply for an interconnection agreement amendment and get approval from your utility to ensure compliance with NEM rules.

  • Answer: Typically, you'll need to submit an interconnection application amendment, updated single-line diagrams, and potentially other documentation specific to your utility. The good news is that we can help you with all of that.

Storage Batteries:

  • Answer: Yes, you can add a storage battery, but it must be configured correctly to ensure it doesn't affect your NEM status. The storage system must primarily charge from your solar panels, not from the grid.

  • Answer: The storage battery should be configured as a non-exporting device, meaning it does not send stored energy back to the grid. This can be ensured through system settings and proper installation practices.

  • Answer: Yes, you must inform your utility and possibly submit an amended interconnection agreement. Some utilities have specific forms and processes for adding storage systems.

Cost and Incentives:

  • Answer: Yes, there are federal and state incentives, including tax credits and rebates, for adding solar panels and storage batteries. The specifics depend on your location and the current incentive programs.

  • Answer: No, adding a storage battery should not affect your eligibility for existing incentives. In fact, there may be additional incentives available specifically for energy storage systems.

System Performance and Monitoring:

  • Answer: Many solar inverters and storage systems come with monitoring software that allows you to track your system's performance. Ensure that any new equipment is compatible with your existing monitoring setup.

  • Answer: This depends on your original installer and the equipment warranties. It's important to review your warranties and consult with your installer to understand any implications.

System Performance and Monitoring:

  • Answer: The main pitfalls include failing to get proper approvals, misconfiguring your storage system, and exceeding capacity limits that could transition you to a less favorable NEM program.

  • Answer: The approval process duration varies by utility, but it typically takes several weeks. It's important to plan ahead and submit all required documentation promptly.

  • Answer: Contact your utility provider's customer service or NEM department. Additionally, consulting with your solar installer can provide guidance specific to your system and local regulations.
