Learn About Solar

Solar Energy Resources

Everything you need to understand how solar works, its benefits, and how projects come together — written for everyone.

How Solar Helps the Environment

Solar energy is one of the cleanest ways to produce electricity. By generating power from the sun instead of burning fossil fuels, solar helps protect the environment while powering homes and businesses.

Clean Energy, Cleaner Air

Solar panels produce electricity without emissions, reducing air pollution and greenhouse gases that contribute to climate change and health issues.

Conserves Water

Unlike traditional power plants, solar systems require little to no water to operate — helping preserve valuable water resources.

Protects Natural Resources

Solar reduces the need for mining, drilling, and fuel transportation, lowering environmental damage and protecting ecosystems.

Low Environmental Impact Over Time

Solar panels offset the energy used to make them within a few years and then generate clean power for decades.

A Sustainable Energy Future

Solar is renewable, reliable, and abundant — helping build a cleaner, more resilient energy system for future generations.

How Solar Helps Communities

Solar energy doesn't just benefit individual homes and businesses — it strengthens entire communities.

Creates Local Jobs

Solar projects create skilled jobs in construction, engineering, and maintenance, supporting local workers and economies.

Keeps Energy Dollars Local

By generating power locally, communities reduce reliance on distant power plants and keep energy spending within the region.

Improves Energy Resilience

Solar paired with battery storage can help critical facilities stay powered during outages, improving community reliability and safety.

Expands Access to Clean Energy

Community solar programs allow residents, renters, and businesses to benefit from solar even if they can't install panels themselves.

Supports a Healthier Environment

Cleaner energy means improved air quality and a healthier place to live and work.

How Solar Helps the Power Grid

Solar energy plays an important role in strengthening and modernizing the electric grid.

Reduces Strain During Peak Demand

Solar produces the most power during the day — when electricity demand is often highest — helping reduce stress on the grid during peak hours.

Provides Local Power Generation

By generating electricity close to where it's used, solar reduces the need to move power long distances, improving efficiency and reliability.

Improves Grid Resilience

Distributed solar systems help create a more flexible grid. When paired with battery storage, solar can support power during outages and grid disruptions.

Supports Grid Stability

Modern solar inverters can help regulate voltage and frequency, supporting stable grid operations.

Delays Costly Grid Upgrades

By reducing peak loads and adding local generation, solar can help utilities postpone or avoid expensive infrastructure upgrades.

Works With Other Energy Sources

Solar complements traditional and renewable power sources, helping build a balanced and reliable energy mix.

How a Solar Site Is Built

A solar site is made up of several key components that work together to turn sunlight into usable electricity safely and efficiently.

1

Solar Panels

Panels capture sunlight and convert it into direct current (DC) electricity.

2

Racking & Foundations

Racking systems hold the panels in place and are anchored to the ground or roof to withstand wind, snow, and weather.

3

Inverters

Inverters convert DC electricity from the panels into alternating current (AC) power used by homes, businesses, and the grid.

4

Electrical Wiring & Equipment

Cables, combiner boxes, and protection devices safely move electricity from the panels to the inverter and beyond.

5

Utility Interconnection

The system connects to the electric grid, allowing solar power to supply on-site energy and send excess electricity back to the utility.

6

Monitoring & Safety Systems

Monitoring tracks performance in real time, while safety equipment ensures reliable operation for decades.

How a Ground-Mounted Solar Site Is Built

Ground-mounted solar systems are designed for open land and are built to deliver reliable, long-term energy production.

1

Site Evaluation & Layout

The process begins with surveying, soil analysis, and system layout to ensure optimal sun exposure and structural stability.

2

Foundations & Racking

Steel piles or ground screws are installed to anchor the racking system, which is engineered for local wind and snow loads.

3

Solar Panels

Panels are mounted onto the racking and positioned to capture the maximum amount of sunlight throughout the year.

4

Electrical Systems

Wiring, combiner boxes, and inverters are installed to safely collect and convert the power produced by the panels.

5

Grid Connection & Testing

The system is connected to the utility grid, inspected, and tested to ensure safe, reliable operation.

How a Rooftop Solar System Is Built

Rooftop solar systems turn unused roof space into a source of clean, reliable energy.

1

Roof Assessment & Design

Engineers evaluate roof condition, orientation, and shading to design a system that maximizes performance without compromising the structure.

2

Mounting Hardware

Specialized mounts are securely attached to the roof structure and sealed to protect against leaks.

3

Solar Panels

Panels are installed on the mounts and arranged to capture sunlight efficiently while maintaining a clean, low-profile appearance.

4

Inverters & Electrical Equipment

Inverters convert the power for use in the building, while electrical equipment ensures safe operation and code compliance.

5

Utility Interconnection & Monitoring

The system is connected to the grid and equipped with monitoring so performance can be tracked in real time.

Frequently Asked Questions

Answers to common questions about solar energy, the installation process, and working with Helios Energy.

How long does a solar installation take?
Project timelines vary based on system size and type. Rooftop installations typically take a few days to a couple of weeks, while larger ground-mount or canopy projects may take several months from permitting through commissioning. Our team will provide a detailed schedule during the project planning phase.
What types of solar projects does Helios Energy specialize in?
Helios Energy specializes in commercial and utility-scale solar EPC across New England, including canopy systems (parking structures, schools), rooftop systems, and ground-mounted solar farms. We also install energy storage systems and EV charging infrastructure.
What is an EPC contractor?
EPC stands for Engineering, Procurement, and Construction. An EPC contractor manages all three phases of a solar project — designing the system, sourcing the equipment, and performing the construction — providing a single point of accountability from start to finish.
What incentives are available for solar projects in New England?
Federal, state, and utility incentives vary by location and project type. These can include the federal Investment Tax Credit (ITC), state rebate programs, net metering, and SMART (Solar Massachusetts Renewable Target) in Massachusetts. See our Incentive Programs section for more detail.
Does Helios Energy handle permitting and interconnection?
Yes. Our project management team handles permitting, utility interconnection applications, and coordination with local authorities, ensuring a smooth process from approval through energization.
