NSolV8 — The New Standard in PV Sizing

NSol! has been the standard for sizing off-grid PV and PV-generator hybrid power systems since 1993 —
now NSolV8 is here! 

Notice:
Effective 8 June 2020, NSolV8 has replaced NSolVx. The price for the new version will be US$250 and will include a license for operation on a single computer.
Customers who have purchased NSolVx within the past 12 months (Serial Number 5001259 and higher) qualify for a free upgrade. This upgrade must be completed before 31 Dec 2020, after which the upgrade will cost US$150.
Customers who have owned the software for less than three years (Serial Number 5001226 and higher) are eligible for a reduced price for the upgrade. The upgrade price is US$150. Customers who have owned the software more than three years must purchase a license at the full price of US$250.

After 31 Dec 2020, the upgrade price will apply only to users who have owned the program for less than three years.

Customers who have a license which previously allowed two installations per serial number will need to purchase a separate upgrade for each user.
NSolVx will continue to work, even if the new software is installed. We will support re-installation of NSolVx on replacement computers for a period of one year — until 7 Jun 2021.

NSolV8 has been updated to enable detailed, accurate system design across a wider range of applications. 

NSolV8 is better than ever …

Flexible user interface

All major sizing functions are on the one screen, allowing even quicker evaluation of system options.    Simply select the appropriate tab, change the component and view the system result on the summary screen. Most tables and graphs can be directly copied to the clipboard for easy export to proposals.

Quick sizing

Once you have selected a site, chosen components, set basic system factors and selected an array tilt, you can size a system by clicking on the [Auto PV] and [Auto Batt] buttons.

Loss-of-Load-Probability Analysis

No more guessing about battery size.  The advanced LOLP statistical analysis shows you the exact effects of increasing battery and array sizes in standalone PV systems.

Expandable insolation database

Now includes NASA data for every integer latitude and longitude.  All sites now include temperature data. Users can search by country, region/state, city, or latitude / longitude.

Component Databases

User modifiable databases for PV modules, batteries, controllers (new) and inverters (new).  A new database structure allows quick searching, sorting and filtering of data.

Updated Battery Analysis

Now allows user to specify standard Lithium or LiFePO4 batteries. More accurate analysis of batteries allows the advanced user to set parameters such as average charge voltage.

New System Configurations

Now includes AC bus PV and AC Bus hybrids in addition to DC Bus PV, DC Bus hybrids and Mixed Bus hybrids. NSolV8 now allows the user to enter a custom load profile for AC systems.

Updated reporting

Reports include detailed information and a personalized logo (new) as well as customized company contact information.

Improved export of data

There are eighteen different graphs and tables — you can right-click on the graphs to copy them to the clipboard, and right click on the data tables to copy them into a spreadsheet (new).  You can also export a detailed data set for further analysis.  It is easier than ever to use NSolV8 to generate proposals and system manuals.

Grid-Tied systems

NSolV8 integrates grid-tied system design into the same user interface that made NSol! famous.  Select a site, a module and an inverter from the database, click on [Auto PV] and the program will automatically do temperature-corrected string calculations to determine the optimal number of modules in series and parallel.
