Description

The Fluke IRR1-SOL Irradiance Meter

 

The Fluke IRR1-SOL Irradiance Meter is a handheld tool that makes it easy to install, test, and maintain photovoltaic systems. It measures irradiance, temperature, inclination, and direction of the solar array in one device. It has a durable design, a protective case, and a high-contrast LCD screen. It meets the IEC 62446-1 standards for solar energy. It also has a compass and an inclination sensor to measure and document the orientation and tilt of the panels.

The IRR1-SOL can help you with:

  • Designing and surveying photovoltaic systems. You can find the expected production and shading at a site by measuring the solar resource in peak sun hours.
  • Measuring the performance of the system. You can check the electrical characteristics and the power output of the array by using the solar irradiance to calculate the IV curve.
  • Comparing and diagnosing the system. You can troubleshoot any issues with the system by ensuring that it receives the correct amount of irradiance energy to generate the DC voltage for the inverter.

The IRR1-SOL is the ideal tool for every solar installer and technician.

Features & Benefits

• Inclination measurement feature lets you establish tilt to determine the best orientation
• Built-in compass means it’s simple to find the cardinal direction, for a full picture of site conditions
• High-contrast LCD screen makes results easy to read, even in direct sunlight

Applications

• Roof-mounted panels
• Large photovoltaic installations

How is this device powered?

This meter is powered by four AA alkaline batteries, which typically have a life of 50 hours or over 9,000 readings.

📦 UK Delivery Options

We work with both Royal Mail and DHL to offer reliable and flexible delivery across the UK:

  • Royal Mail – Best suited for lighter parcels and for customers in remote regions, including the Highlands, Islands, and Northern Ireland.
  • DHL – Ideal for most mainland UK orders, providing fast, tracked delivery and excellent reliability for time-sensitive shipments.

Our checkout system automatically displays the available delivery services for your postcode and order weight, ensuring you always see the most suitable options.

Note: Heavy, bulky, or freight-only orders will be charged separately.
Our website is designed for quick, transactional purchases rather than bulk or palletised orders.
Please contact us in advance for a tailored freight quotation if your order falls into this category.


⏱ Dispatch & Delivery Timing

We aim to dispatch all in-stock orders promptly, but delivery depends on both when you order and which service you select.

  • UK orders: placed by 2:00 PM Monday–Friday are usually dispatched the same day.
  • International orders: placed by 2:00 PM Monday–Thursday are usually dispatched the same day.

Orders placed after these times are processed the next working day. This means delivery may occur the following day or later, depending on the courier and service selected.

Once dispatched, your chosen delivery service determines how quickly your parcel arrives:

  • Standard services We use Royal Mail Tracked 24 or DHL Parcel as our ‘Standard’ services. They are not guaranteed to arrive next working day.
  • Premium services (e.g. Royal Mail Special Delivery or DHL by Noon) offer guaranteed delivery windows.

If your order is time-sensitive, we strongly recommend choosing a guaranteed service or contacting us before ordering to confirm availability.

Please note: For logistical reasons, we may occasionally adjust the delivery method selected at checkout. For example, smaller items may be better suited to letterbox-friendly packaging or may be at greater risk of delay or loss via certain services. We actively monitor courier and postal service disruptions—including strikes and delays—and may modify shipping arrangements to help ensure timely and secure delivery.


📅 Busy Periods & Delays

We always aim to dispatch promptly, but delivery times may be affected by:

  • Seasonal demand (e.g. Christmas, bank holidays, or industry shutdowns)
  • Courier network delays outside our control
  • Supplier lead times or calibration requirements for certain equipment

If your delivery is time-critical, please contact us before ordering so we can confirm stock and courier availability.


🌍 International Shipping

We ship worldwide using UPS Express Saver® and other trusted global courier partners. All international shipments are tracked and generally dispatched Monday to Thursday to ensure smooth customs clearance and transit.

Estimated delivery times:

  • Europe: 1–2 working days
  • North America: 2–3 working days
  • Asia-Pacific & Rest of World: 3–5 working days

Delivery times vary depending on location, customs clearance, and local courier performance.


💰 Taxes, Customs & Import Duties

International customers are responsible for any applicable taxes, customs charges, or import duties.
These are not included in our product or shipping prices.
