Step 1: Define Your Energy Goals

Before you start ordering panels or sketching layout ideas, you need to get crystal clear on one thing: how much energy do you actually need?

Understanding your energy goals is the foundation of any successful project solar installation. Here’s how to break it down:

Analyze Your Electricity Usage

Start by reviewing your electricity bills—ideally from the past 12 months. Look for the total kilowatt-hours (kWh) used per month. This gives you an annual average to work with and helps size your system accurately.

➡️ Pro tip: In the U.S., the average household consumes about 10,000–12,000 kWh per year. But your needs could vary based on home size, climate, and appliances.

Decide on Your Coverage Rate

Do you want to:

  • Cover 100% of your energy usage?
  • Just offset your peak hours or a specific appliance?
  • Stay grid-tied or go fully off-grid?

Your answer will shape everything from panel quantity to battery sizing.

Factor in Future Needs

Are you planning to buy an EV soon? Add a heat pump? Your project solar system should account for potential upgrades.

Step 2: Evaluate Your Roof and Space

Once you know how much energy you want to generate, it’s time to see where your solar system will live. Your roof—or available outdoor space—plays a crucial role in the success of your project solar installation.

Check Orientation and Tilt

  • South-facing roofs (in the Northern Hemisphere) get the most sun exposure.
  • The ideal tilt angle depends on your location but usually ranges between 15°–40°.
  • Flat roofs? No problem—mounting systems can create the correct tilt.

➡️ Not sure if your roof is ideal? Our AceFlex Premium Solar Kit includes a full K2 Systems mounting report tailored to your home.

Watch Out for Shading

Trees, chimneys, and even neighboring buildings can block sunlight and reduce system efficiency. Use tools like the SunCalc app or consult a shading analysis to evaluate your site.

Measure Available Space

You’ll need roughly 100 sq ft per 1 kW of solar panels. If you’re planning a 6 kW system, that’s about 600 sq ft of usable roof area.

➡️ Panels like the Trina or Axitec are compact and powerful—ideal for tight rooftops.

Structural Considerations

Ensure your roof is:

  • In good condition (no major repairs due soon)
  • Structurally sound for added weight
  • Accessible for safe installation

If you’re unsure, consider getting a roofer or structural engineer to check it out before installation.

Step 3: Choose the Right Components for your Solar Project

With your energy goals set and your roof evaluated, it’s time to choose the right components to bring your project solar installation to life. This is where the performance, efficiency, and long-term value of your system are determined.

Solar Panels

Start by selecting high-efficiency solar panels that fit your space and budget. Consider:

  • Wattage per panel (e.g. 425W)
  • Panel type (monocrystalline is ideal for residential projects)
  • Aesthetics (black frame vs. silver frame)

AceFlex offers a curated range of U.S.-compliant panels.

Each option is designed for long-term durability and high output, even in partial shade conditions.

Inverter

The inverter is the brain of your solar system. It converts DC energy from the panels into usable AC power for your home.

Options include:

  • String Inverters – cost-effective for unshaded roofs
  • Microinverters – ideal for complex layouts or partial shading
  • Hybrid Inverters – for systems with battery storage

Popular models in our shop include SolarEdge, Enphase, and Sol-Ark inverters.

Looking for a streamlined solution? Our Solar Kit Basic is a great starting point, offering flexibility to select your preferred panels, inverter, and wiring—ideal for flat or simple pitched roofs.

Step 4: Plan Wiring and Safety Features

Wiring is the invisible backbone of your solar installation. A solid wiring plan ensures that your system operates efficiently, safely, and in full compliance with U.S. electrical codes.

AC vs. DC Wiring

Most solar systems generate DC (direct current), which is then converted to AC (alternating current) by the inverter. Your wiring plan needs to address:

  • String configuration (for string inverters)
  • AC branch circuits (for microinverters)
  • Proper cable sizing to reduce voltage drop

AceFlex offers ready-made Wiring Essentials Packages—available in Small, Medium, and Large—that include key components like:

  • EZ Solar XL Rooftop PV Junction Box (JB-1.XL)
  • Conduit fittings
  • Grounding lugs
  • Labels and disconnects

These packages are designed to meet NEC requirements and simplify your installation.

Safety First: Required Disconnects and Protection

A compliant solar setup must include:

  • Rapid shutdown devices
  • AC/DC disconnects
  • Overcurrent protection (fuses or breakers)
  • Proper grounding and bonding

Some utilities also require a revenue-grade production meter or smart monitoring integration.

Tip: If you’re not familiar with electrical safety standards, we strongly recommend working with a licensed electrician for final connections, especially for grid-tied systems.

Step 5: Check Permits and Grid Connection

Even the most well-planned solar installation needs to comply with local regulations. Before installing your system, make sure you handle all required permits and utility approvals to avoid delays or legal issues.

Local Permitting Requirements

Most U.S. municipalities require one or more of the following:

  • Electrical permit
  • Building permit
  • Solar-specific installation permit

Contact your local permitting office early in the planning process to learn:

  • Which forms are needed
  • Whether plan reviews or inspections are required
  • If licensed professionals must be involved

Tip: Some jurisdictions offer online permitting for solar systems, which can speed up the process significantly.

HOA and Zoning Considerations

If you live in a neighborhood with a Homeowners Association (HOA), check whether exterior modifications like solar panels require prior approval. Similarly, make sure your system doesn’t violate zoning regulations regarding height, setback, or aesthetics.

Interconnection with the Utility Grid

For grid-tied systems, you must apply for interconnection approval with your local utility. This typically involves:

  • Submitting a system design and equipment list
  • Installing a utility-compatible inverter
  • Passing an inspection or commissioning test

Once approved, your system can send excess power back to the grid—often earning you credits through net metering, where available.

Important: Utilities vary widely in their approval process and timeline. Factor this into your project schedule.

Step 6: Installation and Monitoring of your Solar Project

With your components selected, permits approved, and utility paperwork in motion, it’s time for the final step: installation. This is where your project solar vision becomes a working reality.

Installing Your Solar System

Depending on your system type and roof complexity, installation typically includes:

  • Mounting the racking system to your roof structure
  • Securing the solar panels
  • Routing DC/AC wiring
  • Installing the inverter and combiner boxes
  • Connecting the system to your main service panel

AceFlex Solar Kits include detailed component guides—and our Premium Kit comes with a custom K2 Systems mounting plan for even more precise guidance.

Note: While many steps of the installation can be handled by a confident DIYer, the final AC connection to your main panel should always be performed by a licensed electrician.

System Activation and Testing

Once the system is connected and inspected (if required), your utility may give permission to operate (PTO). After that, you’re ready to go live.

Power production typically starts immediately, especially on grid-tied systems.

Monitoring Your System

Most modern inverters include web portals or smartphone apps that show real-time:

  • Energy production
  • Usage trends
  • Alerts or error messages

Popular monitoring platforms include:

  • Enphase Enlighten
  • SolarEdge Monitoring
  • Sol-Ark Dashboard

Monitoring is essential to ensure your system operates efficiently and detects any drop in performance early on.

FAQ: Planning Your Own Project Solar Installation

Do I need an electrician to install a DIY solar system?

While many parts of a DIY solar installation—such as mounting panels and running DC wiring—can be done by a skilled homeowner, the final AC connection to your main service panel must be performed by a licensed electrician in most U.S. states. This ensures compliance with code and avoids safety risks.

Can I get tax incentives for installing my own solar system?

Yes. The federal Investment Tax Credit (ITC) allows homeowners to deduct a percentage of their solar system costs from their federal taxes—even if the system is self-installed. Local incentives may also be available depending on your state. Always keep detailed receipts and consult with a tax advisor.

What’s the best inverter for a DIY solar project?

It depends on your system design. Microinverters (like Enphase) are ideal for complex or shaded roofs. String inverters (like Fronius or SolarEdge) are cost-effective for open, unshaded layouts. Hybrid inverters (like Sol-Ark) are best if you plan to integrate battery storage.

How long does a typical home solar installation take?

For DIYers, a basic 5 to 10 kW system can often be installed over one or two weekends. More complex installations with batteries or structural adjustments may take longer. Make sure you allow time for permitting and utility approval, which can add several weeks.

Can I expand my system later if my energy needs change?

Yes. Most solar systems are scalable. If you anticipate future upgrades (like an electric vehicle or heat pump), choose an inverter and mounting layout that allows easy expansion. At AceFlex, we help customers plan for long-term flexibility from the start.
